Answer 2

Let's solve each of the given expressions step by step:

1. +2 + 0 = 2 The result of adding 2 and 0 is 2.

2. (+21) + (-21) = 0 The result of adding 21 and -21 is 0. When you add a positive number and its negative counterpart, they cancel out.

3. 55 + (-45) = 10 The result of adding 55 and -45 is 10.

4. +46 + (-49) = -3 The result of adding 46 and -49 is -3.

5. -12 + (-12) = -24 The result of adding -12 and -12 is -24.

6. (-4) + 84 = 80 The result of adding -4 and 84 is 80.

7. 0 + (-48) = -48 The result of adding 0 and -48 is -48. When you add zero to any number, it remains the same.

8. (+39) + (+39) = 78 The result of adding 39 and 39 is 78.

9. -23 + (-42) = -65 The result of adding -23 and -42 is -65.

10. (-97) - 3 = -100 The result of subtracting 3 from -97 is -100.

11. 91 + (+9) = 100 The result of adding 91 and 9 is 100.

12. -22 + 22 = 0 The result of adding -22 and 22 is 0. When you add the opposite numbers, they cancel out.
