b) 25 - (12-(3x2 +1)] =​

Answer 1

Resposta:

a) 16+ (10 - ( 18:3+ 2) + 5) =28.666...

b) 25 - (12-(3x2 +1)] =8

Answer 2

Resposta:

a) 16+ [10 - (6 + 2) + 5 ] =

16 + [ 10 - (4) + 5 ] =

16 + [ 10 -4 + 5 ] =

16 + [ 6 + 5] =

16 + [ 11] =

16 + 11 = 26

b) 25 - [ 12 - (6 + 1)] =

25 - [ 12 - (7)]=

25 - [12 - 7 ] =

25 - [5] =

25 - 5 = 20
