Answer 1

a)1+(8-3) = 6
b)5+(1+1) = 7
c)(9-2)+(3+1) = 11
d)(8+3)+(1+1) = 13
e)(6-3)+(1+1) = 5
f)(5+2)-(1+1) = 5
g)(8-4)-(5-1) = 0

Answer 2

A) 1 + (8-3) = 1 + 5 = 6
B) 5 + (1+1) = 5 + 2 = 7
C) (9-2) + (3+1) = 7 + 4 = 11
D) (8+3) + (1+1) = 11 + 2 = 13
E) (6-3) + (1+1) = 3 + 2 = 5
F) (5+2) - (1+1) = 7 - 2 = 5
G) (8-4) + (5-1) = 4 - 4 = 0
