The Order of Operations is very important when simplifying expressions and equations. The Order of Operations is a standard that defines the order in which you should simplify different operations such as addition, subtraction, multiplication and division.
This standard is critical to simplifying and solving different algebra problems. Without it, two different people may interpret an equation or expression in different ways and come up with different answers.
The Order of Operations is shown below. Before we begin simplifying problems using the Order of Operations, let's examine how failure to use the Order of Operations can result in a wrong answer to a problem.
Without the Order of Operations one might decide to simplify the problem working left to right. He or she would add two and five to get seven, then multiply seven by x to get a final answer of 7x. Another person might decide to make the problem a little easier by multiplying first. Without a standard like the Order of Operations, a problem can be interpreted many different ways. As we walk through the steps to simplifying this expression, use the Order of Operations reference in the right column of this page.
The first step in the Order of Operations is to simplify parentheses and brackets from the inside out. You must remember to use the Order of Operations when simplifying the inside of the parentheses, but we don't need to worry about that in this problem because there is only one operation inside the parentheses 3 - 1.
In this case all that has to be done is subtraction of 1 and 3. The answer is shown below. The next step in the Order of Operations is to simplify exponents. The result is shown below. The next step in the Order of Operations is to simplify multiplication and division in the order that they appear.
There is no division, only multiplication. Multiply 2 and Again, the first step in the Order of Operations is to simplify parentehsis and brackets from the inside out.

Homework 1 Homework 2 Homework 3 Practice Worksheets What works well here too is to outline the problem by simply labelling the order in which you are going to do the operations then proceed with it. Practice 1 Practice 2 Practice 3. Math Skill Quizzes The scores on these might suprise you, if students haven't had some practice on the skill first.
Quiz 1 Quiz 2 Quiz 3. The website also provides immediate feedback and error correction, which is very helpful. AAA Math provides a great deal of information on order of operation. There is an instruction section, a practice section, and a play section. The practice section provides you with a problem which you must solve. This site also provides immediate feedback. In the play section on this website, the same types of problems are used in the practice section, but there are goals like determining how many problems can you do in 60 seconds.
This is great for students that are around grades three or four. This is such a fun game. There is a square with 16 smaller squares, each of which holds a number.
Enter an equation - the helper breaks the equation into each step required by the order of operations. Unlimited replay and review.
Homework: Order of Operations · ÷ Use “pemdas” to help simplify each expression. Check your work on a calculator and record keystrokes if your answers do not match each other. 1. 8 + 7 · 9 12 + 42 2. 35 – (17 – 2) ÷ 5 24 – 9 · 2 + 6 ÷ 3 3. 90 – 22 45 + 3 28 – 11 9 4.
Homework: Order of Operations · ÷ Use “pemdas” to help simplify each expression. Check your work on a calculator and record keystrokes if your answers do not match each other. The order of operations is a very simple concept, and is vital to correctly understanding math. Unlike reading, where we always work left-to-right, sometimes problem math we need to work one part of a problem before another, or the final answer could be incorrect!
