If all we have are the whole numbers, {0, 1, 2, 3…}, we can find this difference 5 – 2 = 3 but we can’t find this difference 2 – 5 = ? To find the difference 2 – 5 we need to expand our set of numbers. Copyright 2015 Scott Storla

Integers have two attributes, a “size” (how much, how many) and a sign (positive or negative). For instance $2 has a size of 2 and it’s positive, we have $2. – $2 also has a size of 2 and it’s negative, we owe $2. To discuss the size of a number we use the absolute value operator.
