## What you’ll learn to do: Correctly use the order of operations

What is [latex]3+5\times2[/latex] ? Is it [latex]13[/latex] or [latex]16[/latex] ? This may seem like a trick question, but there is actually only one correct answer.

Many years ago, mathematicians developed a standard **order of operations** that tells you which calculations to make first in an expression with more than one **operation**. In other words, order of operations simply refers to the specific order of steps you should follow when you solve a math expression. Without a standard procedure for making calculations, two people could get two different answers to the same problem, like the one above. So which is it, [latex]13[/latex] or [latex]16[/latex] ? By the end of this module you’ll know!
