There are two types of Inverse Properties. The Inverse Property of Addition and the Inverse Property of Addition.

The Inverse Property of Addition is when you add a number and its opposite resulting in zero. Therefore, in order to understand the Inverse Property of Addition, you must understand a numbers opposite.

Examples) 5 + -5 = 0 or A+ -A= 0

The Inverse Property of Multiplication means to multiply a number by its reciprocal. Therefore, to fully understand this property you must first understand what it means to find the reciprocal of a number.

Examples) 7 * 1/7=1 or A * 1/a=1

Notice that in each example the first term is not written as a fraction, but as a whole number. I could write 7 as 7/1 as well.
