Math+8

Your Math 8 Final Exam is just around the corner!!!

In order to review all of the rules and steps that we have built up all year long, I give you the Math 8 forum in "SESM for Dumees."

What to do?
 * 1) Click on the EDIT link in the top right corner of this section in order to open up the "Editor" toolbar.
 * 2) Add any of the following to the appropriate section for each Math 8 Unit:
 * Math Rules.
 * Create your own Math question. You must already have checked the solution.
 * You may answer another students question by showing the work to get the solution.
 * You can find online resources that help teach a Math concept. See the "Expanding Brackets" Youtube video in the Algebra Unit below.
 * 1) Include your name after any addition to the Wiki. Use only your first name and last initial. DO NOT USE YOUR FULL NAME.
 * 2) Happy Reviewing!!! Summer is so close, I can smell it.

When __Multiplying__ Fractions, Cross cancel and then multiply numerator by numerator and denominator by denominator. Express in lower terms if needed. When __Dividing__ fractions, Change the division sign to multiplication and flip the following fraction. Then same steps as Mulitplying Fractions. ~ Candice R. :D
