Mrs. Sol's Class: Order of Operations

This week in math we're learning about the Order of Operations.

Numbers

and Operations

in a Formation...

Watch this video and you'll see what I mean!

Do NOT blame me if that song is stuck in your head until 2034.

Many things in math are not up for interpretation. We need to agree on certain math rules in order for for humans to calculate numbers and communicate accurately.

For example, if you are ordering new carpet and the guy at Carl's Carpet Center asks you what the square footage of your bedroom is, you should both have an understanding of area. If you calculate differently, you may end up with too much or not enough lime green wool shag. (I had lime green shag carpet in my bedroom when I was your age, so don't laugh.)

"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." (algebrahelp.com)
