Question

Simplify the following.
a. 4+ [19+{7+3 - 8+9}]
b. [8 + 9 + {5+ (19 - 4) = 3} + 4] - 12
c. 14 [24 + (8 - 2) + 3 (7 - 4)]
d. 241 - 18+ (7 X 12 - 61) - 8
of 40
2
e. 29 - (21 + 7) + (27 + 32) -
f. 5[{(81 +9) X 12 - 18} - 6]
g. 63 = 3 -12 + 7 + 6
h. [7x{17 - 12-8-6} = 7]​

Answer 1

Answer:

a. 4 + [19+[7+3-8+9]

= 4+ [19+[10-17]

= 4 + [19+ [7]

= 4+19×7

= 4+133=137

Answer 2

Answer:

Simplify the following.

a. 4+ [19+{7+3 - 8+9}]

b. [8 + 9 + {5+ (19 - 4) = 3} + 4] - 12

c. 14 [24 + (8 - 2) + 3 (7 - 4)]

d. 241 - 18+ (7 X 12 - 61) - 8

of 40

2

e. 29 - (21 + 7) + (27 + 32) -

f. 5[{(81 +9) X 12 - 18} - 6]

g. 63 = 3 -12 + 7 + 6

h. [7x{17 - 12-8-6} = 7]

Step-by-step explanation:

(8+9+{5+(19-4) =3}+4) -12
