How can I remember the order of operations in math?

A great way to remember the order of operations is to use the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right).

What does each part of PEMDAS mean?

Sure! 'P' stands for Parentheses, which means you solve anything inside parentheses first. 'E' is for Exponents, which are powers or roots. Then, you do Multiplication and Division from left to right, followed by Addition and Subtraction from left to right.

Can you give me an example problem?

Of course! Let's solve: 3 + 5 × (2^2 - 1). First, solve inside the parentheses: 2^2 is 4, so it becomes 3 + 5 × (4 - 1), which is 3 + 5 × 3. Then, multiply: 5 × 3 is 15, so finally, 3 + 15 equals 18.

Are there any tricks to remember PEMDAS?

Yes! You can use a mnemonic like 'Please Excuse My Dear Aunt Sally' to help remember the order. Each word corresponds to a part of PEMDAS.
