Again, the first step in the Order of Operations is to simplify parentehsis and brackets from the inside out. Now we can simplify the second innermost grouping symbol, the bracket using the Order of Operations. First simplify multiplication and division in the order they appear. Now remove the parentheses symbols and simplify addition and subtraction in the order that they appear combine like terms. Now, start using the Order of Operations to simplify the polynomial inside of the second set of parentheses.

There are no exponents on the inside so you can skip to simplifying multiplication and division in the order the appear. The division comes first in this expression, so divide 3 by 2 first. Now that the inside of each set of parentheses and brackets are simplified, the problem can be worked on as a whole instead of in little groups.

Now in step two of the Order of Operations, simplify the only exponent in the expression, 3 2. There are no terms which can be combined, this problem is complete. Evaluate any addition and subtraction from left to right or which ever way makes it easier for you:.

As always evaluate the expression within the parentheses first, since there is more than one operator in the parentheses, apply PEMDAS to the expression. Negative Exponents An introduction to the meaning of negative exponents.

Order of Operations Lessons The Order of Operations is very important when simplifying expressions and equations. Parentheses and Brackets -- Simplify the inside of parentheses and brackets before you deal with the exponent if any of the set of parentheses or remove the parentheses. Exponents -- Simplify the exponent of a number or of a set of parentheses before you multiply, divide, add, or subtract it. Multiplication and Division -- Simplify multiplication and division in the order that they appear from left to right.

Addition and Subtraction -- Simplify addition and subtraction in the order that they appear from left to right. Order of Operations Parentheses and Brackets from the inside out Exponents of numbers or parentheses Multiplication and Division in the order they appear. Addition and Subtraction in the order they appear. Example 1 Evaluate the following. Step 1 First, evaluate whatever is in the parentheses: Step 2 Next, evaluate the exponent: Step 3 Evaluate any multiplication and division from left to right: Step 4 Evaluate any addition and subtraction from left to right or which ever way makes it easier for you: Example 2 Solve for x in the equation below.

When they have agreed that an expression is correct they fill out the team chart, which I make on a different color paper - one for each math family team, and send someone in their group to write it on the class chart in the back of the room while other members continue checking another expression. I really want groups to keep trying to write expressions for the numbers that their team did not come up with yet. I try to challenge them by saying things like: Each team has a different color marker and periodically I will go check for mistakes on the large chart and go get that team to figure it out.

Students from other teams also notice mistakes and bring them to my attention. When I do white boards I have them all raise their boards at the same time. What that means though is that some students finish earlier than others. Later in the year I will put up "stretch" problems for them, but this early in the year I want them to get into the practice of helping each other. They instead should be looking to see if they all agree or if they or someone needs help.

Students are allowed to begin their homework in class as soon as they get it. I ask the class why they think I did not tell them in the directions to use the correct order of operations.

Some will be confused by the word evaluate and need to be reminded that it means to find the value or the answer. Sign Up Log In.
