Answer 1

Respuesta:

1) 55

2) -29

3) -31

Explicación paso a paso:

1) {15 + 3{-4.(10.4 - 200 ÷ 5 + (-3)} + (15 - 10) + (-1)}

{15 + 3{-4.(40 - 40 - 3} + 5 - 1}

{15 + 3{-4.-3} + 4}

{15 + 3{12} + 4}

{15 + 36 + 4}

55

2)

10.2 - 8 ÷ 2 + 3{4.2 - 5.3} + (-6 + 3).8

20 - 4 + 3{8 - 15} + (-3).8

16 + 3{-7} - 24

16 - 21 - 24

-29

3)

5.(-7 + 3) - 12 ÷ (-4) + 20 ÷ (1 - 6) - 4 - 6

5.(-4) + 3 + 20 ÷ (-5) - 10

-20 + 3 - 4 - 10

-31
