Question

A
(4 —3 . 2 + 7 ) : ( —1 ) — 18 : ( —4 —2) =

B
(—7—1) . (2—5) + 5 . (—3) =

Answer 1

A

$(4 - 3 \times 2 + 7) \div ( - 1) - 18 \div ( - 4 - 2) = - 2$

B

$( - 7 - 1) \times (2 - 5) + 5 \times (- 3) = - 71$

$\boxed{HoLa}$

Explicación paso a paso:

A)-

$(4 - 3 \times 2 + 7) \div ( - 1) - 18 \div ( - 4 - 2) = \\ \\ 4 - 6 + 7 \div ( - 1) - 18 \div ( - 4 - 2) = \\ \\ - 2 + 7 \div ( - 1) - 18 \div ( - 4 - 2) = \\ \\ 5 \div ( - 1) - 18 \div ( - 4 - 2) = \\ \\ - 5 - 8 \div ( - 4 - 2) = \\ \\ - 5 - 18 \div (- 6) = \\ \\ - 5 - ( - 3) = \\ \\ - 5 + 3 = \\ \\ - 2$

B)-

$( - 7 - 1) \times (2 - 5) + 5 \times ( - 3) = \\ \\ - 8 \times (2 + 5) + 5 \times ( - 3) = \\ \\ - 8 \times 7 + 5 \times ( - 3) = \\ \\ - 56 + 5 \times ( - 3) = \\ \\ - 56 - 15 = \\ \\ - 71$
