►This site was originally created for my kids and their cousins, because we did science together. We eventually added more friends and I ended up having science classes for five years. I am no longer adding to the site (since 2014), but will leave it up for others' use. I do post to facebook occasionally if I come across something to share. =)

►Please accept my apology for any broken links or videos that do not work. I am always disappointed when people take down their videos from YouTube. It makes it hard to find just the right replacement. And because the videos were posted years ago, I usually have no recollection of what the video was about.
I kept thinking I would have time after my kids graduated, but life has filled up my free time with new responsibilities. =)

►Please do not email, asking me to post your website link, or to review something to put on my site. Any resources posted on this site are things I had found on my own during my regular searching for material I needed at the time, and liked it well enough to post here. There have never been any affiliates on my site, and as it is no longer active, would not be worthwhile at this point. ;)
Thank you!

Rules for Exponents

There are a lot of videos here!  About 35 minutes total, so I suggest taking more than one day to watch these, and taking notes as you do. The first several videos are shorter.


Interactive lessons -- may be best to do after viewing the videos here.

You may read along with the lesson in the left sidebar.

(1) Product Rule


(2) Quotient Rule


(3) Power Rule


(4) Using the rules


(5) Simplifying fractions with exponents


(6) Exponents, powers of base 10


(7) Level 1 Exponents, part 1 - the "why" of some of the above, and a few new concepts.


(8) Level 1 Exponents, part 2

In the last example, he leaves "3 to the negative 36th power." 3^-36, (since I can't write exponents on here except for °²³).  I have been taught and have seen taught in various videos online that you should try to not have a negative exponent in your answer.
In the 5th video, she showed how to get rid of negatives by moving the negative exponent to either the top or bottom of a fraction.  So the last answer could be written as a fraction: 1/3^36.  "1 over 3 to the 36th power."
