3.9 + (6 + 5 - 3) - 12:4
2{117+1(5.3 - 9) - 3(-10 - 8)}
5 - [6 - 2- (1-8) - 3+ 6] + 5
(3 - 8) + 5- (-2)

Answer 1

Explicación paso a paso:

A)27 + 3 - 45 : 5 + 16=

=27+3-9+16

=30-9+16

=21+16=37

B)3.9 + (6 + 5 -3) - 12:4=

3.9+6+5-3-12:4

27+6+5-3-3

=32

C)2{117 + 1(5-3 - 9) - 3(40 - 8)}

234+-10×32

=14

D)5 - [6 - 2 - (1 - 8) - 3+6] + 5

5-[6-2-(1-8)-3+6]+5

5-[6-2+7-3+6]+5

5-6+5 =4

E) (3 - 8) + (5 - (-2)]

(3-8)+[5+2]

(3-8)+[7]

(-5)+[7] 3-8

=2
