(4+32+6)+(10-32-2) 300:4+300:6-25 17.[39(-111)]+29.(-17) 19.43+(-20).43-(-40) Giải giúp em vs ạ

~~ Bạn tham khảo nhé ~~

`(4 + 32 + 6) + ( 10 - 32 - 2)`

`= 4 + 32 + 6 + 10 - 32 - 2`

`= (32 - 32)+ (4+6 + 10 - 2)`

`= 0 + 18 = 18`

`300/4 + 300/6 - 25`

`= \frac{900}{12} + \frac{600}{12} - 25`

`= \frac{1500}{12} - 25`

`= \frac{1500}{12} - \frac{300}{12}`

`= \frac{1200}{12} = 100`

`17 . [39 . (-111)] + 29 . (-17)`

`= 17 . (-4329) - 29 . 17`

`= 17 . [(-4329) - 29]`

`= 17 . (-4358) = -74086`

`19 . 43 + (-20) .43 - (-40)`

`= 43. [19 + (-20)] + 40`

`= 43 . (-1) + 40`

`= -43 + 40 = -3`
