Im struggling with pemdas! With this question especially!

Answer 1

So here's PEMDAS:

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

So we will complete this equation in that order. So first is solving the problem within the parenthesis:

(12) ÷ 4  · 7 - 4² ÷ 4 =?

Then we solve all the parts including an exponent:

12 ÷ 4 · 7 - 16 ÷ 4 = ?

Next, we solve the parts with multiplication:

12 ÷ 28 - 16 ÷ 4 = ?

Then, we solve for all the division:

0.43 - 4 = ?

If there was any addition we would do that next, but because there is none, we move onto subtraction:

0.43 - 4 = -3.57

So, your answer is -3.57
