Question

A = 20 + {4 x 5+ [38 - 2 x 14]}
B = 6 + 9 + 15 - (15 - 3)
C = {52 + [72 - 12 x 9 + 121 - 43​

Answer 1

Answers:

a) = 50

b) = 18

c) = 94

Process:

a)

20 + {4 x 5+ [38 - 2 x 14]}

20 + (20 + (38 - 28))

20 + (20 + 10)

20 + 30 = 50

b)

6 + 9 + 15 - (15 - 3)

6 + 9 + 15 - 12 = 18

c)

{52 + [72 - 12 x 9 + 121) - 43)

52 + (72 - 108 + 121) - 43

52 + 85 - 43 = 94
