Answer 2

1. −5−(−12)−(−4)-5 - (-12) - (-4)−5−(−12)−(−4)
−5+12+4=11-5 + 12 + 4 = 11−5+12+4=11

2. −(−7)+(−14)−(−20)-(-7) + (-14) - (-20)−(−7)+(−14)−(−20)
7−14+20=137 - 14 + 20 = 137−14+20=13

3. (−13)−(−8)+(−15)(-13) - (-8) + (-15)(−13)−(−8)+(−15)
−13+8−15=−20-13 + 8 - 15 = -20−13+8−15=−20

4. 17−(−19)−(25)17 - (-19) - (25)17−(−19)−(25)
17+19−25=1117 + 19 - 25 = 1117+19−25=11

5. −(−13)−(15)+(−20)-(-13) - (15) + (-20)−(−13)−(15)+(−20)
13−15−20=−2213 - 15 - 20 = -2213−15−20=−22

6. (−17)−(−16)−(+23)(-17) - (-16) - (+23)(−17)−(−16)−(+23)
−17+16−23=−24-17 + 16 - 23 = -24−17+16−23=−24

7. −(−25)−(−14)+(−17)-(-25) - (-14) + (-17)−(−25)−(−14)+(−17)
25+14−17=2225 + 14 - 17 = 2225+14−17=22

8. (−14)−(−13)−(+10)(-14) - (-13) - (+10)(−14)−(−13)−(+10)
−14+13−10=−11-14 + 13 - 10 = -11−14+13−10=−11

9. −(−8)−(−15)+(+9)-(-8) - (-15) + (+9)−(−8)−(−15)+(+9)
8+15+9=328 + 15 + 9 = 328+15+9=32

10. −(−15)+(−14)−(+7)-(-15) + (-14) - (+7)−(−15)+(−14)−(+7)
15−14−7=−615 - 14 - 7 = -615−14−7=−6
