Calculator.

 A calculator is a machine which allows people to do math operations more easily. For example, most calculators will add, subtract, multiply, and divide. Some also do square roots, and more complex calculators can help with calculus and draw function graphs. Calculators are found everywhere.

The reason calculators are so fast is that they have no moving parts. The invention of transistors, integrated circuitry and years of refining have led to the modern-day pocket calculators. The earlier vacuum tube calculators would take days what today's calculators can achieve in seconds.

The purpose of a calculator is to do correct calculations, and to do so efficiently. It is clear that a calculator should relieve the user of the need to do mental operations and of the need to rely on paper, so far as possible.

Calculators allow students to work more quickly, which means they can solve more problems in a given time. So you can increase the number and complexity of the problems you introduce in each lesson without increasing the time devoted to problem solving lessons.

A calculator is a device that performs arithmetic operations on numbers. The simplest calculators can do only addition, subtraction, multiplication, and division. More sophisticated calculators can handle exponent ial operations, roots, logarithm s, trigonometric functions, and hyperbolic functions.

When they are a part of teaching pupils mental and other maths skills, calculators can help improve students' maths abilities, the study says, and pupils are more likely to use them less, but in a better way.

This technology allows students solve complicated problems quickly and in an efficient manner. Additionally, it can reduce the problem to simpler tasks and allows the student to devote more time in understanding the problem.

Calculators (and computers) combine inputs using electronic components called logic gates. As the name implies, a logic gate acts as a barrier in an electronic circuit; it takes in two electric currents, compares them and sends out a new current based on what it finds.

The first calculator or adding machine to be produced in any quantity and actually used was the Pascaline, or Arithmetic Machine, designed and built by the French mathematician-philosopher Blaise Pascal between 1642 and 1644.

In 1642, the first true calculator was invented: one that performed calculations through a clockwork-type of mechanism. The Pascal calculator, invented by French inventor and mathematician Blaise Pascal, was lauded for attempting arithmetic calculations previously thought impossible.

A calculator invented in India by Shakuntladevi of Bangaluru, Karnataka in 1980-82 ( 4th November,1929 to 21st April,2013 )

Calculators in the elementary grades serve as aids in advancing student understanding without replacing the need for other calculation methods. Calculator use can promote the higher-order thinking and reasoning needed for problem solving in our information- and technology-based society.

The calculator has had a profound impact on the world, making computations quicker and more exact. In the classroom, calculators have given many students the ability to learn about and put complex formulas and concepts into practice more easily.

Like all other electronic devices, calculators work by processing information in binary form. ... Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.

Solar cells, also known as photovoltaic cells, use energy from light (artificial or real) and turn it into electricity used to power the calculator. USB computer cable: Use the USB computer cable that came with your calculator and a computer to charge your calculator.

calculators are nothing but simple computers and as such are only as good as their coding and will always have some limitations involving for instance rounding. Some errors can be avoided by paying attention to how you enter a problem if you are aware of the flaw in the coding.

A calculator is a small hand-held computer that performs mathematical calculations. Some calculators even permit simple text editing and programming. It is also a program on a computer that simulates a hand-held calculator.

Scott Flansburg (born December 28, 1963) is an American dubbed The Human Calculator and listed in the Guinness Book of World Records for speed of mental calculation.

It's 100,000,000 represented in scientific notation. In this context, a $100M company. 1E8 = 1 * 10^8 = 100,000,000 (xEy = x * 10^y).
