Calcula, aplicando las prioridades de las operaciones.

a) (+3) + (–2) · (+5) =

b) (– 4) + (– 7) · (–2) =

c) (– 5) + (+20) : (– 4) – (–3) =

d) [(– 5) – (–3)] – [ – ( –4) – (– 7)] =

e) (+4) : (–2) + (+8) : (+2) + (+6) · [(+4) + (➖ 5)]​

Answer 1

(+3) + (–2) · (+5)

+3 + (-10)

+3 - 10

-7

(– 4) + (– 7) · (–2)

-4 + (+14)

-4 + 14

+10

(– 5) + (+20) : (– 4) – (–3)

-5 + (-5 ) + 3

- 5 - 5 + 3

-10 + 3

-7

[(– 5) – (–3)] – [ – ( –4) – (– 7)]

[– 5 + 3] – [ + 4 + 7]

[– 2] – [ + 11]

- 2 - 11

- 13
