+227 A calculator is used to evaluate mathematical expressions, such as 2+2 or 3/5. Most calculators convert the entry into binary form, then perform the arithmetic. (Binary is a way of writing numbers and data in 0s and 1s. In binary, our 0=0, 1=1, 2=10, 3=11, 4=100, 5=101, 6=110, and so on.) The expression is then turned back into decimal (the base we usually use) unless you specify otherwise. They are a great improvement and allow some mathematical revelations to be realized due to their power.
