Khan Academy — Summer Math Help

July 1, 2011

Have you heard about the Khan Academy?  You can see YouTube videos of almost all math topics in short, clear clips.  You can easily search for the topic you want help in.  Most of the videos are 10 minutes or less, with you having the ability, of course, to pause or replay part or all of the video.  They are very well done.

The topics go from Arithmetic, Pre-algebra, Algebra, 1 & 2, Geometry, Precalculus, Calculus 1,2 and 3 (multivariables).

Also, Linear Algebra, Differential Equations,  Probability and Statistics,

Salman Khan started with math, and has branched into many different areas, in science and the humanities.
