Hola!

Explicación paso a paso:

400- [30 + 6(19-12)] =

400- [ 30 + 6 . 7 ]

400 - [ 30 + 42 ]

400 - 72

328

(3-8) + [5- (-2)] =

-5 + 7

2

9 [6÷2] =

9 . 3

27

(5+3(2) - 6) (4÷2) + (7-8+4(3))

(5 + 6 - 6 ). 2 + ( 7 - 8 + 12)

5 . 2 + ( -1 + 12)

5 . 2 + 11

10 + 11

21

(15-4) +3 - (12-5(2)) + (5+16÷4) =

11 + 3 - ( 12 - 10 ) + (5 + 4)

11 + 3 - 2 + 9

14 - 2 + 9

12 + 9

21
