f) 26 - (15-8) + (8-3) - 6 =​

Answer 1

Resposta:

a)(37-5+3):(15:3)

$32 + 3 \div 5 \\ 35 \div 7 \\ = 5$

b)49 +(18x2):(27:3) =

$49 + 36 \div 9 \\ 49 + 4 \\ = 53$

c) (72:9) + (14 x 5) - (12 x 2) =

$8 + 70 - 24 \\ 78 - 24 \\ = 54$

d) 180 + (90 - 50) + 15 =

$180 + 40 + 15 \\ 220 + 15 \\ = 235$

e) (14:7 + 6x2) + 38 =

$2 + 12 + 38 \\ 14 + 38 \\ = 52$

f) 26 - (15-8) + (8-3) - 6 =

$26 - 7 + 5 - 6 \\ 26 - 7 - 1 \\ 26 - 8 \\ = 18$
