Question

Use what you know about inverse operations and the Zero Property of Addition to complete each number sentence.

5.9 - _ = 0

3.9 - 0 = _

Answer 1

• 5.9
• 3.9

Explanation:

The subtraction of a number from itself gives zero. The first blank is filled with the number 5.9, so when that value is subtracted from 5.9, the result is zero.

Adding or subtracting zero changes nothing. The second blank is filled with 3.9, the number from which nothing is subtracted.
