Answer 2

Respuesta:

a) (3 - 5) - (15 - 4) = -2 -11 = -13

-2 - 15 + 4 = -13 =- 13

-13 = -13 = -13

b) (16 - 8) - (12 – 7 + 2) =

8 - 12 + 7 - 2 = 1

c) 12 + (6 - 8 - 1) =

12 + 6 -8 -1 = 9

d) 5 - (12 + 8) =

5 - 12 - 8 = -15

e) 40 - (10 - 80) =

40 -10 +80 = 110

f) -(4 - 32 + 13) + 16 =

-4 +32 -13 + 16 = 31

g) - (15 -29) + (10-27) =

-15 +29 +10 -27 = -3

h) -12 + (-8 + 19 – 42) =

.12 -8 +19 -42 = -19

i) 5+ [7 - (3 +16)] = 5+(7 - 19) = 5+(-12) = 5-12 =

5+ [7 - (19)] = 5+(-12) = 5+(-12) = 5-12 =

-7 = -7 = -7 = -7 = -7
