Question

resolva as expressões numéricas.​

Answer 1

Resposta:

a) (4 x 5 + 3) - ( 2 + 8 : 4)

= (20 + 3) - ( 2 + 2)

= 23 - 4

= 19

b) 7 + (2 x 3 - 1 ) + (10 - 9 : 3)

= 7 + (6 - 1) + (10 - 3)

= 7 + 5 + 7

= 19

c) 6 + ( 15 : 3 x 12)

= 6 + ( 5 x 12)

= 6 + 60

= 66

d) (30 x 5 + 4) - (12: 6 + 8)

= ( 150 + 4) - (2 + 8)

= 154 - 10

= 144
