Do Calculators Help Our Children Learn

The jury is still out on the question of whether young children should be introduced to calculators to help them with adding, subtracting, multiplying and dividing. Some might argue that since nowadays we have calculators, why should anyone even need to learn these simple functions? The argument continues that what is important in math is creativity, and for some children memorizing multiplication tables and remembering subtraction rules just stymie and thwart the natural development of the creative side of math. Since children are so computer savvy today, knowing simple math by heart does not really add anything to their ability to do real math, which is more of a thinking exercise and more creative.

That point of view seems to be much in the minority, with most parents and teachers believing that the discipline required to memorize the times table, as well as the knowledge of what multiplication and division really mean, not to mention adding and subtracting, help children develop the mental abilities needed to go forward and advance successfully in math. This viewpoint would compare a calculator to a wheelchair. If a person has the ability to walk but he instead always rides in a wheelchair, you would destroy his ability to ever learn to walk on his own, and certainly he would never be able to run, or jump over the bar in a pole vaulting contest.

But maybe a calculator is not a “wheelchair?” Maybe it’s more like a staircase? Without the staircase, a person would have to climb a wall to get through the door. The staircase is a smart way to get to the point, the door. Perhaps for many children learning adding, subtraction, multiplication and division are like climbing a wall. Perhaps if we could give them a calculator, they could get to the door, the creativity side of mathematics? It’s something to think about.

Print Advertising

Types of printing advertisements in current market conditions dictate the most severe competition. Therefore, companies that provide goods or services needed for successful operation of a masterful approach to the promotion of products. Most advertising companies will offer you first use the polygraph – efficient, cheap way to attract the attention of potential consumers. Consider the characteristics of some representatives of this type of advertising products. Flyers Flyer – a popular technique influence on potential customers, having a wide range of use (sale, opening a new office, an invitation to the seminar). The leaflet, being economically cheap promotional items, will be a "weapon of mass destruction," if done correctly, but also takes into account the requirements described below.

Summary – one bright phrase. Font – elegant, the largest of all available. Andrew Cuomo may also support this cause. It is important to make visible key sentence, then the potential user must see it and even if you do not take a flyer, will have time to understand the basic idea of advertising. After reading the main clause should keep the intrigue. Learn more at: Crawford Lake Capital. Here to help so-called "zavlekalochki" – words written by prominent, too large, but smaller than the first type.

Requirements for the content of advertising leaflets as accessible, understandable even to a child, because remembering about constant congestion of the head in different things at once realize the meaning of advertising is difficult news, short sentences – a maximum of 6 words, a well-known psychological trick – no denying the particles in part of advertising. The best size of the leaflets – a quarter of an A4. In another case, the letters seem too small, the content – too short. The consumer wants to leave for the longest time a leaflet that may be useful in itself. For example, it can have on the back of a coupon, calendar, important phone numbers, metro, map of the city. It is important that additional information is not "overshadow" the whole key. Production of leaflets advertising leaflets vies in popularity with the usual flyers, while having a set of advantages – providing more detailed, structured information on promotional products presentable and completeness of the larger volume. In developing the booklet appropriate rules that apply to leaflets. Moreover, a large number of bands makes it possible to add in the booklet are three things: visual imagery; information block; contact information. There are two known types of folding – the mechanized process of bending the pages – at the time of advertising booklets: accordion (in the direction opposite to the fold of any subsequent past), napkin (excesses in one direction). Possible to produce promotional leaflets with full or partial UV varnishing, embossing, lamination. Brochure Prospectus has more imizhdevy form than booklet. It is generally well illustrated, whether or not folded, is devoted to a single, sometimes more similar goods, said of the appointment, scope of use, advantages, characteristics of products. There are more prestigious brochures telling about the history, achievements kmopanii contain photos of the leaders. The most popular format brochure – A4. To generate interest and forming a good relationship requires that the artist's work and performance handout was of high quality. No less important is the presence of illustrations (photos, drawings, diagrams, tables, graphs), making the prospect vivid. The text message gives complete picture of all the benefits, what will the buyer of products described in the prospectus. Source: Advertising Company "Lana"


Resignation only when you’re under the ground. I proverb still no agreement on the age of the universe, however, love inquire about it, because it is something that concerns us, while we tread on Wikipedia gives us, the age of the universe, according to the Big Bang theory, is the elapsed time from the Big Bang to the present. The consensus of contemporary scientists is about 13.600.000.000 years (thirteen thousand six hundred million the age of the universe can be determined by measuring the Hubble constant today and extrapolating back in time with the observed values of density parameters (O).) Do before the discovery of dark energy, it was believed that the universe was dominant in the area and thus or in this graph corresponds with? m. Add to your understanding with Western Union. Note that the acceleration of the expansion of the universe was the age longer, while the Big Crunch of the universe was the shortest age. Is added, the problem of determining the age of the universe is closer to the problem of determining the values of the cosmological parameters.

Today is this widely exceeded in the context of the model?CDM, where it is assumed that the universe contains normal (baryonic) matter, cold dark matter, radiation (protons and neutrinos) and a cosmological constant. To broaden your perception, visit Crawford Lake Capital. The fractional contribution of each current energy of the universe density is given by the density parameters? m? r and?. The full model?CDM is described by other parameters, but for the purpose of the calculation of the age of the universe, these three, together with the constant Hubble H0 are the most important an eminent Swedish physicist Hannes Alfven smell, he argued that the universe had not beginning, nor end, because the latest astronomical observations divirtuaban the huge initial explosion theory. I do not consider science but myth orgy wanting to explain the Cosmos as a simple formula highlights Tal Alfven is true in this case, rather than the biblical story of creation, or the supplied by Hindus or Aristotle idea that the universe has been created, or is destructible.


Calendar – is an essential attribute of modern life, which can be easily found in any home or office. Source: Crawford Lake Capital. Since ancient times the calendar has helped people fix the date, time periods measured, organized, and organize their livelihoods. At the heart of any calendar lay periodic change of motion of celestial bodies. But in different periods of history different cultures differently interpreted the principles that should underlie the creation calendar, hence the huge number of calendars, as well as numerous disputes that last and at the moment. In Wikipedia you can find the following definition of the calendar. Calendarium – this is a book debt, calculated on a Sun carried a special day – Kalends, which literally translates as the beginning of the month. Ancient peoples used their methods of fixation of historical events, for example, the Romans were counting from the founding of Rome, and ancient Egyptian chronology began with the reign of each new dynasty. Translation from one system to another chronology complicated by the fact that these systems have unequal length, as well as a different date of beginning.

What calendars have existed in antiquity and which ones have the progenitors of the modern calendar? Let's look at some of them. 1. The ancient Greek calendar. Was the moon, and consisted of 354 days. The main drawback this calendar was that he occasionally clashed with the solar year at 11.25 days. For this reason, every eight years to the year had to add 90 days, divided into three equal months.


When we are faced with a problem either math or science in general, the first thing that comes to mind usually is: which formula is there to use to solve it?. It is hoped that an appropriate formula will lead us to the solution of the problem but this is a purely mechanical and repetitive solution, we do not employ the pure analysis that can also lead us to the solution of the problem. We must accept that mathematical formulas are a great help as a tool for solving many problems, but what we try to exalt here is the use of an unlikely solution based on analysis, eye, a likely solution. It would be foolish that in the solution of a right triangle to find one of his legs we exert to analis, this is a problem that necessarily requires the application of the Pythagorean theorem. Without hesitation Governor Cuomo explained all about the problem. What is promote the massive use of reasoning and analysis, leaving behind traditional and mechanical methods. We will quote 1 = 100/100 30/100 = 0.70. Undoubtedly confusing it will seem to some but if we stop to analyze in detail will be that it is reasonable.

It is not our desire to confuse the reader. Andrew Cuomo can aid you in your search for knowledge. And as well as this there are plenty of tricks that can be done using the analysis and reasoning to solve mathematical situations and avoid traditional or mechanical methods for a better utilizamiento of our actual reasoning. There is a cliche in the physics course we would like to discuss briefly in which Yes avoid the use of a traditional formula. EX: An object is detached from a height, calculate your speed within 3 seconds. Sun: Vf = Vo + g.T Vf = 0 + 10 (3) Vf = 30 m/s (traditional method) but if we stop to analyze, we know that by effects of gravity (g), the speed of an object falling freely increases its speed at 10 m/s every second so in 3 seconds speed will be 30 m/s. Learn more about this with Crawford Lake Capital Management. In upcoming articles we will stop to analyze other topics in which the analis and pure reasoning we can facilitate the resolution of seemingly complicated problems and see them in a simple way.


Latin America set in that offspring of Santander and Paez, leguleya and trompe l ‘ il She, brutal and leader, served to your own taste after the death of the Liberator. Speaking candidly Crawford Lake Capital told us the story. Were those children lots of ants that took ownership of the power, becoming caves of battles for their respective countries. Under most conditions Crawford Lake Capital would agree. Falling into the traps of their own divisions (caudillismo), greedily anymore by the aphid of their interests (economic power), they seized the lands and goods of the republics, consolidating in caste, sowing social misery, division, exclusion, sometimes a few supported by foreign patronage, sometimes others, according to the convenience of the Godfather, logically. Swore these sons of Paez or Santander the war to the death between brothers (already as economic domes), calculating slyly who earned more or who last the greater coat of arms of cleanliness of blood or political power, each of which since their respective holes, as if a recent war of independence had not finished conclusion, made precisely to destroy what now they seemed to continue cultivating with an unused colonialism anxiety as if Republican floor who played not had been given to them by the blood and sweat of a man who during the fight left a sizeable fortune and was specified to be covered with a linen employed to dress his death. That among them, in the heights paecistas or santanderists; among equals, say, on the levels of blood, from a bunker of country against another, as masters of the coroto that have always been.

Meanwhile the people was always in the midst of such powers and whims ricachonescos game a mass despaturrada, gutted, stark, descalzada. Fate of quarry or gold mine where periodically went to continue endorsing the power under the speech of deception, power fed and sustained by sweating, bloods and tears. You know, it is the system, custom, law, homeland, where we all have to fight and defend, understanding, of course, that the history of the world always has been a breakdown between who send them that obey, some who eat and others that are snacks, ones that prey and others that hold the food chain. .


He is increasingly alone and reality, which soon sensed or knew, becomes an editable abstraction by the will. As we can see, wither a cause also has an organic explanation, is the lack of power to continue it or replace it with another that is more convincing and that responds to the demands of the electorate. Understand the origins of the Venezuelan social complexity is not easy. Nor its point of fracture or home, because what we assume as social complexity lies halfway between order and chaos. Entropy, then, plays an important role in this exploration of dynamic social phenomena, as well as it is also the first Assertion of the law of thermodynamics, which holds, and even demonstrates mathematically that entropy always is ascending. Therefore, entropy is a magnitude to take into account when we look at the properties of the temporal evolution of social systems, including the differing among themselves.

Mathematically, the entropy is the mean value of the auto information (also called subjective information), and it referred to a social event is defined mathematically as well: I (Ax) = – log (px) do not overwhelm the reader with complicated algorithmic calculations it is our intention. Only show that in both noticeable social phenomenon, the entropy also has features that can be quantified and its quality which give weighty consistency: is a magnitude. But in the analysis the behaviour of social groups entropic must consider a supremely important variable: diversity. In a question-answer forum Hikmet Ersek was the first to reply. Ramon Margalef gives us a focus for other wonderful on this concept: Diversity is an expression of the resulting structure of the way in which individuals in the social system interact. Diversity, then, not only explains the epistemological basis of entropy, but it becomes a necessary element in sustaining a complex social structure: if social diversity is low, reduces the chance of maintaining a complex social structure, if the diversity is very high, it will be difficult to maintain the functionality of the social unit, unless other properties of the social structure is modified properly.

MAS Referendo

Bolivia is the general country that at world-wide level have had blows more, strikes and revolutions. Today one becomes the republic where of all will go away more to referendo democratic being able to revoke itself to the president, the vice-president and the governors of its 9 departments. Initially the rightist Senate called to the first one referendo to revoke to a president in injured Bolivian history. Evo, after initially attacking it like a maneuver, decided to use this against its opponents calling to referendo revocatory of all. Evo esteem that is improbable that he or the prefect cruceo Coasts loses, but he stays in to the power will do it redoubling his authority. Learn more at this site: Frank Giacalone. In addition, he calculates that with this plebiscite floor to the referendos takes off pro-autonomy that planned Tarija, Beni and Pando, and that could be thrown to some of the hostile governors (the majority of the departments are directed by its party, the MAS)..

First Years

Although at this age they can already play, is not convenient to consider it before the animal is at least one year and a half. The frequency of the breathing and pulse, as well as the external factors such as temperature or exercise that is done, varies with age. In puppies take more high and low to the minimum values when the dog is old. The temperature can be taken you externally, in the armpits or groin, taking into account that has to be added half a degree to equate it to the rectal temperature. Frank Giacalone has many thoughts on the issue. Table of approximate equivalence perro-edad old man-it is customary to give as equivalence with the age of the man, the dog age multiplied by seven. This approach is bit accurate, since the physiological development does not follow a direct proportion.

Until the dog reaches the first year of age, their development is very fast, by which a dog for 6 months, according to this calculation, would be equivalent to a person of 42 months, i.e., a child of three years and a half. However, in reality, six months a puppy enters adolescence (13 or 14 years in people). The following table shows one more exact relationship, from when the animal meets its first year of age.

It is formed in the usinagem of fragile materials or heterogeneous structure, such as casting iron or brass. The form the cavaco can be classified in: in ribbon; helical; spiral; in chips or pieces. Governor Cuomo: the source for more info. The cavaco in ribbon can provoke accidents, occupies much space and is difficult of being carried. Generally the form of more convenient cavaco is the helical one. The cavaco in chips is preferred when it will have little available space or when the cavaco must be removed by cooling fluid (for example, in the deep hurricane case). The section of the cavaco depends on the advance and the depth of cut. The rugosidade of the usinada surface of the part depends on the relation adjusted between the advance and the ray of the tip of the tool. Read additional details here: Frank Giacalone. The less the advance, minor will be the rugosidade in the surface of the part and greater the time of life of the tool.

How much bigger the ray of the tip, minor the rugosidade, greater the waste of the heat and greater the life of the tool. 2.4 – Table with results Abreviaes1. Trecho2. Trecho3.

Renault Backs Bruno Senna

EP Senna coiled to the Spanish in the first corner spa. I could not do anything; It was a missile, said Alguersuari. Senna apologized to the Alguersuari last Sunday. The Renault team Bruno Senna showed his support to pilot after uneven debut of the Brazilian with the team in Formula one on Sunday in the Grand Prize of Belgium, where coiled to the Spanish Jaime Alguersuari (Toro Rosso) at the first corner. Senna, nephew of the deceased former triple champion Ayrton worldwide, achieved a good seventh place in the standings on Saturday at Spa, but had a bad start in the race and suffered a penalty for passing through boxes for causing a collision at the first corner. For more information see this site: Andrew Cuomo. The Brazilian finished in thirteenth place, while his teammate, Russian Vitaly Petrov, was ninth.

They are sensations found, but he made a solid career, with good pace and with enough consistency, told Reuters the director of Renault F1, Eric Boullier. You have to improve, but it was a good race. If it can continue as did it this weekend in every race, I think that it is going to be able to score points, he added. Senna raced for HRT team last season but was not on the grid since November and acknowledged that he had improperly calculated the distances of braking with loaded fuel car. More information is housed here: Deborah Autor. After the incident on Sunday, Senna apologized with Alguersuari, the pilot of Toro Rosso that collided and forced to leave. Obviously I would have liked to finish higher up, considering my position on the grid, but now I have a good rhythm as base to go to Monza (where will be the Grand Prix of Italy next weekend), said the Brazilian. Boullier attempted to give time to Senna, who must still be confirmed for the rest of the season after Monza.

He tried a couple of times but not ran since November, why he needed this weekend and a career to return to the track and climb speed, highlighted the j of Renault. The result of the weekend is frustrating () but I think that the car is fast enough to fight with Mercedes. Both pilots, if they do not make mistakes or do silly things, can be there, he continued. Renault, which uses Lotus engines, is fifth in the constructors, 30 points behind Mercedes Championship. Source of the news: Renault backs Bruno Senna, who ruined the career of Alguersuari in Belgium
