Answer 1

1. 4 + 7 = 7+ 4 (B)
11=11
2. 5 + 9 = 9 + 5 (B)
14=14
3. -3 + 5 = 5 + (-3) (B)
2=2
4. -6 + 4 = -4 + 6 (S)
-2=2
5. -8 + 7 = -7 + (-8) (S)
-1=-15
6. 0 + (-2) = -2 + 0 (B)
-2=-2
7. -8 + (-10) = -10 + (-8) (B)
-18=-18
8. 16 + (-9) = -9 + 16 (B)
7=7
9. -27 + (-38) = -38 + (-27) (B)
-65=-65
10. -210 + 168 = -168 + 210 (S)
-42=42
