This document explains the order of operations using the acronym PEMDAS. It defines each term in the acronym: parentheses, exponents, multiplication, division, addition, and subtraction. For each term, it provides an example mathematical expression to demonstrate the correct order of operations. The goal is to explain how to properly evaluate expressions by following the PEMDAS rule of first dealing with items in parentheses, then exponents, then multiplication/division from left to right, followed by addition/subtraction from left to right.

2. Parentheses The thing you do first in a problem (if there are any). Example: (5*3)+21=36

3. Exponents The little number over the big number to show how many times you multiply the big number. Example: 2 2 +6=10

4. Multiplication The little x that shows instead of adding the numbers your multiplying them. Example: 2x8+9=25

5. Division Division is instead of multiplying the numbers you divide them. Example: 21/3+14=21

6. Addition When you put the two numbers together with an addition sign (+). Example: 243,759+72=243,831

7. Subtraction Instead of mixing the numbers with addition we separate them with subtraction (-).
