Question

Resolva as expressões:

Answer 1

Resposta:

A) 7 - 3 + ( - 4 )

4 + ( - 4 ) = 0

B) ( - 4 ) + ( - 3 ) - ( - 5 )

( - 7 ) - ( - 5) = - 2

C) - ( - 15 ) - 14 + 89

15 - 14 + 89

1 + 89 = 90

D) - 13 + 23 - ( - 15 )

10 - ( - 15 ) = 25

E) - ( - 99 ) + ( - 67 ) + ( - 23 )

99 - 67- 23

32 - 23 = 9

F) 23 + ( - 121 ) + 223 - ( - 13 )

23 - 121 + 223 + 13

- 98 + 223 + 13

125 + 13 = 138

G) - 14 + 56 - ( - 33 )

42 + 33 = 75

H) ( - 103 ) + 150 - 23 - ( - 14 )

47 - 23 + 14

24 + 14 = 38

I) 45 - ( - 66 ) + 124

45 + 66 + 124 = 235

J) 55 - ( - 232 ) + 22 - ( - 121 ) + 22 - ( - 31 )

55 + 232 + 22 + 121 + 22 + 31 = 483

É nois :)
