Inverse Operations 1-3
Inverse operations: mathematical operations that undo each other.
Using the same number, the operation of subtraction undoes the operation of addition
Similarly, the operation of division and multiplication can be described as inverse operations
The addition and multiplication properties of 0 and 1 lead us to the subtraction and division properties of 0 and 1
Subtraction Property of Zero
For any whole number a,
a – 0 = a and a - a = 0
Division Property of One
For any whole number a, except 0,
a ÷ 1 = a and a ÷ a = 1
Division Property of Zero
For any whole number a, except 0,
0 ÷ a = 0
Notice in the division property of 0 that the divisor, a, represents any whole number, except for 0.
