Answer:
- 56 - 20 = 36
- 28 + 11 = 39
- -19 - (-10) = -11
- -37 + 15 = 52
- 17 + 12 = 29
Step-by-step explanation:
I'm sorry, I used a calculator.
But here's a tip:
Ex:
1. __ - 20 = 36
Add number 36 and 20
36 + 20 = 56
To check: 56 - 20 = 36
Another Example:
Ex:
5. 12 - __ = 29
Subtract number 12 from 29.
29 - 12 = 17
To check: 17 + 12 = 29
for number 3, I don't how to explain. i'm really good at integers. ;(
If this helps...
WELCOME!
