1. (+3) + (-2) = 1
2. (-4) + (-6) = -10
3. (-14) + (+5) = -9
4. (-8) + (+8) = 0

Hitunglah.

1. (+2) – (+9) = -7
2. (+1) – (-5) = 6
3. (-6) – (-17) =11
4. 0 – (-12) = 12

Hitunglah.

1. (+5) + (-18) + (-5) = -18
2. (-9) – (-8) + (-4) = -5
3. 2 – 7 = -5
4. -4 – 5 = -9
5. -2 + 10 – 5 = 3
6. 3 – 7 – 4 + 8 = 0
7. 16 – (+17) – 13 = -14
