## Introduction

PEMDAS is an acronym that represents the order of operations in mathematics. It is essential to follow this sequence to solve mathematical expressions correctly. Let’s dive into what PEMDAS stands for and how it is used.

## P – Parentheses

Parentheses are used to group numbers and operations together. When solving an expression, start by simplifying what is inside the parentheses first. For example, if you have (2 + 3) x 4, you would add 2 and 3 together before multiplying by 4.

## E – Exponents

Exponents are used to represent repeated multiplication. After dealing with parentheses, simplify any exponents in the expression. For instance, in the expression 2^2 + 3, you would first square 2 before adding 3.

## M – Multiplication

Multiplication comes before addition and subtraction in the order of operations. If you have an expression like 2 + 3 x 4, you would multiply 3 and 4 before adding 2.

## D – Division

Division also comes before addition and subtraction. If you have an expression like 10 ÷ 2 x 3, you would divide 10 by 2 before multiplying by 3.

## A – Addition

Addition is the next operation to tackle. In an expression like 2 + 3 x 4, you would add 2 to the result of 3 x 4.

## S – Subtraction

Subtraction is the last operation to perform. If you have an expression like 8 – 2 + 4, you would subtract 2 from 8 before adding 4.

## Conclusion

PEMDAS is a crucial tool for solving mathematical expressions accurately. By following the order of operations, you can avoid errors and arrive at the correct answer. Remembering what PEMDAS stands for can help you excel in math and other problem-solving tasks.
