How does all this math fit together? The resource creates a graphical view of the extent of mathematics. The map shows the pure and applied sides of studying mathematics and breaks them down into their many disciplines.

If you love algebra, then you're gonna love this balancing method! Introduce young chemists to the algebraic method of balancing chemical equations using a video from an informative chemistry  playlist. The narrator works five...

Were complex numbers discovered or invented? A video presentation makes the case for the discovery of square roots of negative one. In order for complex numbers to be real, then they must behave like other numbers, which they do in terms...

Here is an example in this video of graphing a hyperbola centered at the origin. First, Sal shows solving for the equations of the asymptotes and then shows how to determine the direction of the hyperbola. He takes the approach of not...

Continuing with the study of graphing hyperbolas, Sal shows an example of graphing a parabola that is centered at a point off the origin. By looking at the equation, first without shifting it, he helps listeners develop an intuitive...

You're trapped in a dark castle with a pile of gold coins that a wizard will only allow you to leave with if you can solve his riddle. Math learners solve the riddle of the dark coin with the help of an engaging instructional video.

In this video on the Binomial Theorem, Sal tries to give an intuition behind why combinations are part of its definition. By looking at the expansion of (a + b)3 and carefully looking at where each value originates from, one can see how...

Continuing with the lesson on compound interest, in this video, Sal derives the general formula for any amount of principle, interest rate, and compounding periods over one year.

Sal continues to look at changing the length of compounding time, from daily to hourly compounding interest. Now he is able to show that compounding 100% annual interest converges on the number 2.71É or e as the number of compounding...

Teaching chemical equations can be quite a balancing act! Bolster your class' balancing abilities using a video from a helpful chemistry playlist. The resource explains the theory behind balancing, then shows viewers how to accomplish it...
