Question

5.
Let's simplify.
a) 48 - {30 - (17 + 5)} = 2
b) 27 + {12 - (3 + 6)} x 5
c) 37 + {35 - (4 - 7 + 8)} - 10
d) 48 – 15 = {3X(-2 - 4 + 11)} + 12
e) 7 x 50 = {30 - (5 X 12 + 6 + 5) + 10}
f) 5 x 12 = [-12 = {15+ (4 – 13)}]
g) 10 [25 - {8 – 6(16 - 13}}]
h) -19 + [27 - {14 + (5 - 2) X 4 = 2}] i) 56 - 7 -3 [4 + {8-414 +
j) -72 = 9+ (11 x {10 = (15 - 17 - 14)}]
k) 100 - 2 [500 = 5 {6 + (21 + 7 – 24)}]
1) 300 = 25 (56 - 7 {24 -2(6 - 5-9)}]​

Answer 1

Answer:

given below

Step-by-step explanation:

a)
