Here’s a list of links to videos and other resources that will help as you review key algebraic skills.
1. Manipulating Expressions
2. Rules of Exponents/Logarithms
- Negative Exponents (video)
- Fractional Exponents and Their Usefulness (video)
- Fractional Exponents and How They Work (video)
- Log Rules (Link to PurpleMath.com)
- A unique perspective on exponents and logs by ViHart (a.k.a. the COOLEST video I’ve ever seen about logs)
3. Important Formulas
- Quadratic Formula. Here’s an Introduction (video), a Proof (video), and a Song (video) to help you remember. If you’re a glutton for punishment with a terrible memory, try this alternate version of the song (video).
- Distance Formula. As Khan explains (video), it comes from the Pythagorean Theorem. And using origami, ViHart can give you an awesome proof of the Pythagorean Theorem (video)!
