## What is PEMDAS?

In arithmetic, PEMDAS is an acronym used to mention the order of actions to be followed while solving expressions having several operations. PEMDAS abbreviation here is P- Parentheses, E- Exponents, M- Multiplication, D- Division, A- Addition, and S- Subtraction.

In this article, you will be learning about the PEMDAS rule to solve mathematics expressions. PEMDAS, also known as an order of operations, is a set sequence to complete operations in an arithmetic expression. There are different situations where everything goes through various steps in an arranged sequence. Consider the following outline. Ria and Ron visited a toy company. They both observed the processes followed in the factory to build toys. Toys are first created. Next, they are made and packed in boxes. Finally, they are monitored for quality before being shipped to stores. Everything is done in a fixed order.

## BODMAS vs PEMDAS

The PEMDAS rule is comparable to the BODMAS rule. There is a difference in the outline because specific terms are known by different names at different places.

## When to use PEMDAS?

When there is more than one action in a mathematical expression, we use the PEMDAS rule. There is a sequence of specific rules that need to be followed while using the PEMDAS method. Once the students get the hang of these rules, they can do multiple steps at once.

Tips to Remember:

- Operations in brackets should be carried out in the beginning.
- Next, we should solve the exponents in the expression.
- Then, move from left to right and carry out multiplication or division, whichever happens first.
- Then, move from left to right and bring out addition or subtraction, whichever comes first.

## How does PEMDAS Work?

If multiple operations are used in any arithmetic expression, we have to initially solve the expressions written in parentheses. After getting cleared of parentheses, we solve multiplication and division operations, whatever occurs first in the expression from left to right. Then, we will get an uncomplicated expression with only addition and subtraction operations. We solve addition and subtraction in left to right order, whatever comes first, and get the last answer. This is how PEMDAS works.

## When do we Apply the PEMDAS Rule?

PEMDAS Rule is implemented for solving difficult mathematical expressions involving more numerous operations like addition, subtraction, multiplication, or division. In order to get a better understanding of the topic, students can practice 5th grade math worksheets by Cuemath. Cuemath is an online learning platform that makes learning engaging and interesting.

## Why Is PEMDAS Important?

Without the PEMDAS rule, there are no other ways to obtain only one accurately correct answer. As a very manageable example, to calculate 2 * 4 + 7, we could multiply primarily and then continue to get 15. we also have the benefit of adding first, then multiply and receive 22. Which answer is accurate? Using PEMDAS will give you the exact and only answer as 15. So, one does not have to worry about failing.

Here’s a summary of the rules given in PEMDAS:

- P as the initial letter means you complete any calculations in grouping numbers first.
- Next, scan for exponents, E. Ignore any other operation and take any numbers with exponents to their particular powers.
- Even though M for multiplication in PEMDAS comes before D for division, these two operations have the same preference. Complete only those two operations in the order in which they occur from left to right.
- Even though A for addition is in PEMDAS before S for subtraction, these two operations also have the same preference. You look for these last two operations from left to right and finish them in that order.

## Conclusion

PEMDAS is a very vital and essential concept of mathematics. It helps students solve numerical problems easily and accurately. PEMDAS will allow students to solve problems very quickly without any confusion. It will boost the student’s logical reasoning and thinking.
