b) (–2) · (–5) + (+4) · (–3) =
c) 10 + (– 4) · (+2) – (+6) =
d) 14 – (+5) · (– 4) + (– 6) · (+3) + (–8) =

Answer 1

Respuesta:

a) 20 – (– 6) · (– 4) =

$=-60\div \left(-3\right)\\=-4$

____________________________

b) (-2) *(-5) + (+4) * (-3) =

$=10+\left(4\right)\left(-3\right)\\=10-12\\=-2$

____________________________

c) 10 + (- 4) * (+2) - (+6) =

$=10-8-\left(6\right)\\=-4$

____________________________

d) 14 - (+5)* (- 4) + (- 6) *(+3) + (-8) =

$=14-\left(-20\right)+\left(-6\right)\left(3\right)+\left(-8\right)\\=14-\left(-20\right)-18+\left(-8\right)\\=8$
