Answer 1

Explicación paso a paso:

2. – 15 + - 7 = -15-7 = -22

3. – 3 – (-7) = -3+7 = 4

4. -16 – 58 – (-96) = -74 +96 =22

5. (-6) (-7) (-10) = 42 (-10) = -420

6. (-17) (-3) 9 (-23) = 51 × 9 (-23)=459(-23)= -10557

7. (-18) : (-3) = 6

8. 1344 : 12 : (- 14) = 112 ÷ (-14) = -8

9. 8 – (4 – 7) = 8 - 4 + 7 =11

10. (-4) – (5 – 7) – (4 + 5) = -4 - 5 +7 -4 -5 = -11

11. (-12) – (12 -5) + (16 – 25) = -12 -12 +5 -16 -25 = -60

12. 2 – [- (7 – 2) + 1] – 4 = 2 + (7-2) +1 -4 = 2+7-2+1-4 = 4

13. – 14 – (15 – 20 – 35) – 11 + (45 – 12 + 2 – 15) =

= -14-15+20+35 - 11-45-12+2-15 = -55
