The inverse, or opposite, operation, of many mathematical operations. The opposite of addition is subtraction, the opposite of multiplication is division, and so on. Finding the square root is the inverse of squares, which we learnt about in a previous lesson on exponents. Keep in mind that a number is multiplied by itself to form its square. The squares of the following whole integers are perfect squares: 1, 4, 9, 16, 25, 36, 49, 64, 81, 100.
