Explanation:

Simplify each integer expression

We evaluate each of the 14 arithmetic expressions step-by-step:

1. \(10 - (+4) = 10 - 4 = 6\)
2. \(3 - (-5) = 3 + 5 = 8\)
3. \(-8 + (-3) = -8 - 3 = -11\)
4. \(-10 - 21 = -31\)
5. \(-9 - (-4) = -9 + 4 = -5\)
6. \(8 - 12 = -4\)
7. \(11 + (-7) = 11 - 7 = 4\)
8. \(6 + (-9) = 6 - 9 = -3\)
9. \(8 - (-3) = 8 + 3 = 11\)
10. \(-8 + (+13) = -8 + 13 = 5\)
11. \(-6 - (+2) = -6 - 2 = -8\)
12. \(-5 - (-16) = -5 + 16 = 11\)
13. \(-9 + (-11) = -9 - 11 = -20\)
14. \(3 - 7 = -4\)
