Question

How do you use PEMDAS?

Answer 1

PEMDAS is the acronym for brackets, exponents, division, subtractions, multiplication. Given two or more operations, the PEMDAS letters series tells you, before the calculation is complete, what you can measure first, second and third.

Answer 2

first you do whats inside the Parenthesis

then you do the exponents

then you multiply

then you divide

then you add

then you subtract

Explanation:

(6–2)+2/3

According to PEMDAS, Numbers in parentheses are the first thing to solve in these types of questions. In this case, we would get:

(4)+2/3

Now, instead of doing the easy thing and going straight to adding 3 with 2/3 (which could alter our answer), we will look to PEMDAS.

Division comes before addition, so we do that first.

So then we get 4+0.67

=4.67

Therefore, whenever faced with a simple equation with just numbers, one should always look to PEMDAS as a method to outline the process with which they solve the question.

In very simple cases, it is also called DMAS, where parentheses and exponents are neglected.
