It is your estimate minus the true value divided by the true value and multiplied by 100. So, % error = (estimate - actual) / actual * 100, in absolute value. For example, if you estimate that there are 90 jelly beans in a jar when there are actually 130 your percentage error is: (90-130)/130 * 1…

Formally, division is defined as multiplication of the inverse. For example, 4 / 2 is a short form for 4 * (2 ^ (-1)). So in general, a / b = a * (b ^ (-1)) and b / a = b * (a ^ (-1)), which suggests that a / b and b / a are not always equal (so division is not commutative).
