“Unpacking” Terms from Parentheses

How do you get math terms out of parentheses? And what happens to those terms when you remove the parentheses?

It seems like the process should be simple. But this issue often plagues students; they keep getting points off on tests, quizzes, homework assignments.  What’s the deal?

The deal is that there’s a specific process you need to follow when taking terms out of parentheses, and what you do hinges on whether there’s a positive sign (+) or a negative sign (–) in front of the parentheses.

But not to worry. This video on this page settles the question once and for all. Not only that, but the video provides a story-based approach that you can teach (if you’re an instructor) or learn (if you’re a student) and remember (no matter who you are). Why? Because stories are FUN and MEMORABLE.

So kick back and relax (yes, it’s math, but you have a right to relax) and let the video show you how this process is done.

And in customary style, I present practice problems (along with the answers, too) at the end of the video so you can be sure you understand what you believe you understand.







Math in movies: Who says math isn’t cool?

Some people say that math isn’t “cool,” whatever that means.

I say that is just wrong. Take a look at a wonderful link I found.

Math is Cool!

It shows a wide range of movies that have math content as part of the story, and it directs you right to the scenes that have the math woven in (check out the Flash links). Check them out and see if you agree that math can be as entertaining as … as … showbiz!

Here is a link to mathematics in the movies.

I enjoyed browsing through these. A few of my favorites are:
