It looks like you've uploaded a worksheet titled
"Subtracting Integers", which contains a series of subtraction problems involving positive and negative integers. Since I can't view images directly, I'll help you solve the problems based on the text you provided.
Let me go through each problem one by one and explain how to subtract integers. The key rule to remember is:
>
Subtracting a number is the same as adding its opposite.
> So:
> $ a - b = a + (-b) $

Problem Set:
1. $ 5 - (-5) = ? $
$ 5 - (-5) = 5 + 5 = 10 $
2. $ -9 - 16 = ? $
$ -9 - 16 = -9 + (-16) = -25 $
3. $ 7 - (-12) = ? $
$ 7 - (-12) = 7 + 12 = 19 $
4. $ 20 - 3 = ? $
$ 20 - 3 = 17 $
5. $ -18 - 14 = ? $
$ -18 - 14 = -18 + (-14) = -32 $
6. $ -10 - (-10) = ? $
$ -10 - (-10) = -10 + 10 = 0 $
7. $ 15 - 2 = ? $
$ 15 - 2 = 13 $
8. $ -6 - 14 = ? $
$ -6 - 14 = -6 + (-14) = -20 $
9. $ (-20) - (-4) = ? $
$ -20 - (-4) = -20 + 4 = -16 $
10. $ 17 - 6 = ? $
$ 17 - 6 = 11 $
11. $ -40 - (-14) = ? $
$ -40 - (-14) = -40 + 14 = -26 $
12. $ 12 - (-3) = ? $
$ 12 - (-3) = 12 + 3 = 15 $
13. $ 3 - 19 = ? $
$ 3 - 19 = 3 + (-19) = -16 $
14. $ -16 - (-10) = ? $
$ -16 - (-10) = -16 + 10 = -6 $
15. $ 18 - (-4) = ? $
$ 18 - (-4) = 18 + 4 = 22 $
16. $ -17 - (-1) = ? $
$ -17 - (-1) = -17 + 1 = -16 $

Summary of Strategy:
- When subtracting a
negative number, change it to
adding a positive.
