Answer 2

Let's solve the given arithmetic expressions one by one:

1. -47 + 47 = 0
2. +82 + (-18) = 64
3. (+43) + (-43) = 0
4. (-39) + (-45) = -84
5. 36 + (-36) = 0
6. 0 + (-35) = -35
7. +94 + 6 = 100
8. -19 + (-19) = -38
9. (+1) + 0 = 1
10. (-9) + (+89) = 80
11. 21 + (-41) = -20
12. -95 + 5 = -90

Keep in mind that a positive number with a positive sign (+) or a negative number with a negative sign (-) can be represented as (+x) or (-x), but the sign in front of the number is not strictly necessary. For example, (+43) is the same as 43, and (-43) is the same as -43.
