Standard or basic calculators possess simple mathematical functions to ease daily math, aiding in common calculations like addition and division. A number's square is the product that results from raising the number to its second power. Squares of numbers are useful and necessary values in higher math, with square calculation usually having its own dedicated key on scientific calculators. Though standard calculators typically do not possess such a key, you can still calculate the square of a number on them by multiplying the number to itself.
