Worksheet Overview

Adding two positive numbers gives a positive answer.


Adding two negative numbers gives a negative answer.




15 + 21 = 36

-15 + -21 = -36


Adding a negative number is the same as subtracting the positive.

The answer may be positive or negative depending on the size of the numbers.



25 + -31 = 25 - 31 = -6

25 + -3 = 25 - 3 = 22


These rules are incredibly important, so make sure that you know them!
