Resuelve: (números enteros)
a) –6 – [2 – (1 + 5)] – (–3 + 1)=
b) (-5) · 6 + [10: (-2) + (-8)] =
c) 10· [4+ (-6)]- (-2)· [12-(-3+7)] =

Answer 1

Respuesta:

a) 0

b) - 43

c) - 4

Explicación paso a paso:

a)–6 – [2 – (1 + 5)] – (–3 + 1)=

-6 - [2 - 6] - (-2)

-6 - [-4] + 2

-6 + 4 + 2 = - 6 +6 = 0

b)(-5) · 6 + [10: (-2) + (-8)] =

(-5) * 6 + [-5 - 8]

-30 + [-13]

-30 - 13 = - 43

c) 10· [4+ (-6)]- (-2)· [12-(-3+7)] =

10 * [4 - 6] +2 * [12 - 4]

10 * [-2] + 2 * [8]

-20 + 16 = - 4
