This document provides a series of math word problems and their solutions. It encourages the reader that they can solve simple addition and subtraction problems involving positive and negative numbers by following some basic "rules". It then lists 15 math expressions with the goal of writing out each solution in words based on those rules. The document aims to build the reader's confidence in solving straightforward math operations involving negative numbers.

1. You can do it.
This part of your brain tells you how.
Use the “rules” to simplify each expression below and write it in words.
1. 8 + (-5) = 3
2. -5 + (-4) =
3. 14 + 7 + (-4) =
4. -6 – 8 =
5. 13 + (-25) =
6. -9 + (- 4) + (-3) =
7. 15 + (-3) =
Eight plus negative five is equal to three.

2. 8. -4 + 4 =
9. 14 – (-5) =
10. 7 + (- 8) =
11. –15 – (-7) =
12.–(-7) + 18 =
13. 23 + (-6) + 2 =
14. -8 – 7 – 12 =
15. -9 + (-5) + 14 + (-6) =
