Question

efetue as seguintes operações.  a) (+1495) ÷ (−23) b) (+58) × (−34 − 19) c) −54 − 43 + 75 d) 25 + (−61) − (−54) e) 200 − 740​

Answer 1

Explicação passo-a-passo:

a)

(+1495) ÷ (−23) = -65

b) (+58) × (−34 − 19)

= (+58)×(-53)

= -3074

c)

−54 − 43 + 75 =-97+75

=-22

d) 25 + (−61) − (−54)

= 25-61+54

= -36+54

= 18

e)

200 − 740

= -540
