Subtraction Properties

Subtraction is not commutative as the order matters.

Eg. 7-5 is not the same as 5-7

Subtraction Properties

Subtraction is not associative as the order of the grouped subtractions matter.

Eg. (9-2)-3 is not the same as 9-(2-3)

Inverse Operations

Inverse means to do the opposite

For subtraction it undoes addition and same with addition it undoes subtraction

Example

• 9+5=14

• Inverse will be either 14-9=5 or 14-5=9

• 20-9=11

• Inverse will be either 9+11=20 or 11+9=20

 $20-17=3$  

20 is the minuend

17 is the subtrahend

3 is the difference
