Question

resolva: (a)-(-6+4-1) (b)-(-3+8) (c)_(-3_1) (d)-6-(-3+2) (e)20_(-6+8)-(-1+3)​

Answer 1

Resposta:

Explicação passo a passo:

(a) - (-6+4-1) = -(- 2 - 1) = -(- 3) = 3

(b)-(-3+8) = - (+5) = - 5

(c)_(-3_1) = - (- 4) = 4

(d)-6-(-3+2) = - 6 - (- 1) = - 6 + 1 = - 5

(e)20_(-6+8)-(-1+3)​ = 20 - (+ 2) - (+ 2) = 20 - 2 - 2 = 18 - 2 = 16
