Question

Evaluate 5 + 6 · 2 – 8 ÷ 4 + 7 using the correct order of operations

A) 22
B) 11
C) 27
D) 5

Answer 1

Do solve this you use PEMDAS. This stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

Because there are no parentheses or exponents in this equation, we go straight to the division.

1) 8 divided by 4 equals two so we rewrite the equation. 5+6 x 2 - 2 + 7.

2) Next in order of pemdas is multiplication. Yes I know that in pemdas multiplication does come before division but it doesn’t matter in this problem which you do first. So now we do 6 x2 =12. We then rewrite the equation 5+12-2+7.

3) lastly, addition and subtraction are grouped together and you can just do it in order of the problem. So we do 5+12=17. 17-2=15. And 15+7=22.

So the final answer is: 22

Answer 2

(A) 22

Explanation:

In solving mathematics using order of operations, BODMAS is a sure compass.

I'll like to work with the decimal point there to mean Multiplication.

Let's fire on!

5 + 6 · 2 – 8 ÷ 4 + 7

I'll like to follow this order:

BRACKET

OF

DIVISION

MULTIPLICATION

ADDITION

SUBTRACTION

The process becomes:

5 + 6 · 2 – 8 ÷ 4 + 7

= 5 + 6 . 2 - 2 + 7

= 5 + 12 - 2 + 7

= 24 - 2

= 22
