A quick lesson on how to write an exponential expression in expanded form. All you have to do is write out the base number the identified number of times as represented by the power. This would be a great support to your lesson on...

So you have a given number in expanded form where you have to multiply that same number several times. Make it a little easier for yourself and write it in exponential form. As long as the number has the same base being multiplied you...

Rounding numbers is an essential skill to have for all math classes. Sometimes those decimal numbers are just too big, and sometimes an answer should only be given out to the hundredths (like money). So watch this video to see the rules...

What is unit rate? How is a ratio converted to unit rate? Really, it's just about getting the denominator of a ratio to be 1. When the denominator is 1, the ratio is a unit rate. Check out this video as the instructor illustrates a few...

This video shows how to convert an equation in exponential form to logarithmic form. The example shown uses base e, and it is converted to an equation using a natural logarithm.

Many learners would look at this decimal division problem and just skip it. Don't let them do that! Figure out how to help your learners master long division. The teacher helps make decimals and long division seem doable.

An example of taking an equation written in exponential form and writing it to logarithmic form is explored in this video.

If your class is studying inequalities, consider this video. The focus is on solving a decimal inequality that has negative numbers in it. A lecturer works through an example problem, commenting on the steps and properties necessary to...
