Question

Simplify (3 × 22) ÷ 6 + [28 – (4)2] = ?

A. 32
B. 46
C. 23
D. 55

I thought it was 31? but not a option so can someone explain please..

Answer 1

Then by that your answer would be 23. The answer is C:)
The reason how i got that answer is by when you multiply 4*4 you will get 16 then subtract that by 28 you would get 12 then divide 66 by 6 you would get 11 then add 11 and 12 then you would get 23.

Hope this helps you out:)

Answer 2

[(3 × 22) ÷ 6 + [28 – (4)²] = 23

Explanation:

We have to simplify [(3 × 22) ÷ 6 + [28 – (4)²]

It can be simplified using PEMDAS rule.

P is parenthesis

E is exponents

M is multiplication

D is division

A is addition

S is subtraction

Firstly we will solve parenthesis i.e 3 × 22 = 66

and [28-16] = 12

So, question becomes : [66 ÷ 6 +12]

=[11+12]

= 23

Hence, the correct option is (c) " 23"
