Question

помогите пожалуйста ​

Answer 1

1) (-19 + 62) + 88 = 43 + 88 = 131

2) (1256 - 874) + (-346) = 382 - 346 = 36

3) (-405 +(-607)) + 358 = (-405 - 607) + 358 = -1012 + 358 = -654

4) 411 + (318 +(-404)) = 411 + (318 - 404) = 411 - 86 = 325

5) -649 + (273 +(-528)) = -649 + ( 273 - 528 ) = -649 - 255 = -904

6) - 921 + (405 - 217) = -921 + 188 = -733
