Basic Functions
Addition
The addition (sum function) is used by clicking on the "+" button or using the keyboard. The function results in a+b. Subtraction
The subtraction (minus function) is used by clicking on the "" button or using the keyboard. The function results in ab. Multiplication
The multiplication (times function) is used by clicking on the "x" button or using the keyboard "*" key. The function results in a*b. Division
The division (divide function) is used by clicking on the "/" button or using the keyboard "/" key. The function results in a/b. Sign
The sign key (negative key) is used by clicking on the "()" button. The function results in 1*x. Square
The square function is used by clicking on the "x^2" button or type "^2". The function results in x*x. Square Root
The square root function is used by clicking on the "x" button or type "sqrt()". This function represents x^.5 where the result squared is equal to x. Raise to the Power
The raise to the power (y raised to the x function) is used by clicking on the "y^x" button or type "^". Natural Exponential
The natural exponential (e raised to the x) is used by clicking on the "e^x" button or type "exp()". The result is e (2.71828...) raised to x. Logarithm
The logarithm (LOG) is used by clicking on the "LOG" button or type "LOG()". Natural Logarithm
The Natural logarithm (LN) is used by clicking on the "LN" button or type "LN()". Inverse
Multiplicative inverse (reciprocal function) is used by pressing the "1/x" button or typing "inv()". This function is the same as x^1 or dividing 1 by the number. Exponent
Numbers with exponents of 10 are displayed with an "e", for example 4.5e+100 or 4.5e100. This function represents 10^x. Numbers are automatically displayed in the format when the number is too large or too small for the display. To enter a number in this format use the exponent key "EEX". To do this enter the mantissa (the non exponent part) then press "EEX"...
...Calculators can perform math functions quickly and easily. The most common functions are addition (+), subtraction (), multiplication (*) and division (/). Press the “=” sign to get the answer. Note that many calculators use different symbols for multiplication (x) and division (÷), and "C" for "Clear"—the erase function.
To use the calculator,
The Simple Virtual Calculator supports the following operations:

...In todays time, calculators in schools are just as widely used as computers are. Since its invention nearly forty years ago, the electronic calculator has evolved from a machine that could only perform simple fourfunction operations ( addition, subtraction, multiplication, division) into one that can now also execute highly technical algebraic symbolic manipulations instantly and accurately. Each new generation of calculators builds on the previous...

...Calculators are a way of doing mathematical equations when used correctly. They are also a useful tool in learning mathematics. The use of calculators have only had part in the benefit of education, and with widespread availability, a full range of sizes, and a price range for any budget there should be no excuse not to own a calculator or restrict the use of calculators. Current issues with calculators have to be dealt...
...Calculator in the Exam Room
Affordable technology is continually reducing the amount of thinking we need to do in daily life. With the widespread popularity of digital watches, for example, we do not need to know how to tell time anymore. Computers, another thought  saving device, are becoming ever more sophisticated with the advent of artificial intelligence software. Recently, technology has been creeping into the classroom. Increasingly, teachers are allowing the use of...
...many scholars has really tried to develop their own computer system, being a calculator or analytical machines. Examples of these scholars include Charles Babbage who is known as the father of computer, Blaise Pascal who developed pascal programming language, Ada Augusta, etc. And Thomas Colmal who was a calculator inventor which is the case study of this project, ie this was based on how a standard and scientificcalculators can be...
