Key Concepts

Order of Operations

This principle, often remembered by the acronym PEMDAS, dictates the sequence in which the parts of an expression should be evaluated: first Parentheses, then Exponents, followed by Multiplication and Division, and finally Addition and Subtraction.

Parentheses

Parentheses are used to group parts of an expression so that the operations contained within them are carried out first, ensuring the correct evaluation of the expression.

Exponents

Exponents indicate that a number (the base) is to be multiplied by itself a certain number of times. They are evaluated immediately after expressions within parentheses, according to the order of operations.

Arithmetic Operations

After dealing with parentheses and exponents, the next step involves performing basic arithmetic operations such as addition and subtraction to simplify the expression.
