com cálculo porfavor ​

Answer 1

Resposta:

a) 7 - ( 1 + 3 ) =

7 - 4 =

= 3

b) 9 - (5 - 1 + 2) =

9 - (4 + 2)=

9 - 6 =

= 3

c) 10 - (2 + 5) + 4 =

10 - 7 + 4 =

3 + 4 =

= 7

d) (13 - 7) + 8 - 1 =

6 + 8 - 1 =

14 - 1 =

= 13

e) 15 - (3 + 2) - 6 =

15 - 5 - 6 =

10 - 6 =

= 4

f) (10 - 4) - (9 - 8) + 3 =

6 - 1 + 3 =

5 + 3 =

= 8

g) 50 - [37 - (15 - 8)] =  

50 - (37 - 7) =

50 - 30 =

= 20

h) 28 + [50 - (24 - 2) - 10] =

28 + ( 50 - 22 - 10) =

28 + (28 - 10) =

28 + 18 =

= 46
