The PEMDAS Rule

Why does 6 – 1 x 0 + 2 /2 =7?

Use the PEMDAS rule to solve.

The Solution

You must have seen this or a similar problem circling around the internet – where very simple arithmetic needs to be done, but the trick is to do it in the right order. This involves you to remember your order of operations from your school days. The best way is to use the PEMDAS rule (sometimes called BODMAS.)

PEMDAS/BODMAS stands for
- Parenthesis (or Brackets)
- Exponents (or Orders)
- Divisions and Multiplications
- Additions and Subtractions

So this rule sets the order of mathematical operations. Looking at our problem, we need to perform Divisions/Multiplications first:

Which gives us:

So the correct answer is 7.

How to solve with Omerus?

This problem is easily solved in Omerus by breaking it down into small chunks and labeling each line item as you apply the PEMDAS rule. Or alternatively, you can add the entire problem in one go and let OMERUS worry about the order of operations.

2 / 2 = 1

Step 1: Let's first divide to get 1

1 x 0 = 0

Step 2: Then we multiply to get 0

6 - 0 + 1 = 7

Step 3: Then we add and subtract to get 7

6 x 1 = 6

Final check: Or we can simply add this entire equation in one line to let Omerus worry about the order of operations
