Answer 2

42+52 = 94
-45+(-52) = -45-52= -97
-45+52 = 7
45+(-52) = 45-52 = -7

Answer 3

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

1. 42 + 52 = 94
2. 94 - 45 = 49
3. 49 + (-52) = -3
4. -3 - 45 = -48
5. -48 + 52 = 4
6. 45 + (-52) = -7

Therefore, the results of the given expressions are as follows:

1. 42 + 52 - 45 + (-52) - 45 + 52 = 4
