Пошаговое объяснение:
1. -18+(-5)=-(18+5)=- 23
2. 10+(-5) =10 - 5=5
3. -33+(-54) = -(33+54)=-87
4. 68+(-72) =-(72-68)= - 4
5. -25+(-712)= -(25+712)= - 737
6. 762+(-34) = 762 -34= 728
7. -20+(-357)+(-54) = - (20+357 +54)= - 431
8. -51+367+(-79)= -(51+79)+367= - 130+367=367-130= 237
9. -12+(-68)+(-41)+(-99) =-(12+68+41+99)= - 220
10. -59+370+8+10=388- 59= 329
