The biggest problem with dividing first is that you get a different answer than if you were to convert it to a fraction

@PurelyDef Not sure what you mean. Can you be more specific? If you follow the Order of Operations, you should NEVER get a different answer.

Watch "Basic Math, Lesson 6 - Fractions" to learn how to do that.

I was wondering if you already did, or will do a segment on negative exponets.

[videomathtutor]

I have not done a video on negative exponents yet (as of Dec. 15th, 2008), but I hope to soon!
