a) 5 + (3 - 1)=​

Answer 1

E) 5 - [3 + (2 - 5)]=

(2-5) = -3

3 + (-3) = 0

5 - 0 = 5

f) 3 - [5 - (4 - 6 )]=

(4 - 6) = -2

5 - (-2) = 7

3 - 7 = -4

g)2 +[8 - (7 - 5) +3]=

(7 - 5) = 2

8 - 2 + 3 -> 8 - 2 = 6 + 3 = 9

2 + 9 = 11

h) -8 + [4 - (7 - 13) - 1] + 5=

(7 - 13) = -6

4 - (-6) - 1 -> 4 - (-6) = 10 - 1 = 9

-8 + 9 + 5 -> -8 + 9 = 1 + 5 = 6

i) - [5 + (1 - 9)]=

(1 - 9) = -8

- 5 + (-8) = -13

a) 5 + (3 - 1)=​

(3-1) = 2

5 + 2 = 7
