Answer 1

1. (+3)×(-25) = -(3×25) = -75

2. 43+(-4) = 43-4 = 39

3. 0:(-100) = 0:100 = 0

4. -64:(-32) = 64:32 = 2

5. (-76)-0 = -76-0 = -76

6. +99:3 = 99:3 = 33

7. -6×(+13) = -(6×13) = -78

8. (-33)+(-6) = -33-6 = -39

9. (+52)-52 = 52-52 = 0

10. -7+(+34) = 34-7 = 27

11. 8-(-32) = 8+32 = 40

12. +1×62 = 1×62 = 62

13. $\frac{3}{10} + \frac{5}{12} = \frac{18 + 25}{60} = \frac{43}{60}$

Всё что смогла, извините. ^^"
