Khan Academy: The Fundamental Theorem of Arithmetic

There are four fundamental theorems of mathematics: arithmetic, algebra, calculus, and linear algebra listed here. Each one is described on this poster or handout. The challenge for a student of math is to figure out why they are...

This video lesson from Khan Academy is designed for high school, or college students, who are enrolled in a computer science course. This lesson provides challenges with prime numbers and actorization, information that will later connect...

This video tutorial lesson [4:17] involves solving for the length of one of the legs of a right triangle using the Pythagorean theorem.

This video tutorial lesson [4:32] uses the Pythagorean theorem to find the hypotenuse of a right triangle in an application problem.

This video walks through the "Fundamental Theorem of Arithmetic".

Video lesson explaining why the antiderivative is the area under a curve. Provides an introduction to the fundamental theorem of calculus. [9:46]

This video [4:48] shows how to determine the integral of an unusual function using geometry to find the area under the curve. Also shows how to find the derivative of a function which contains an integral by using the Fundamental Theorem...

This video tutorial [13:03] explains that the Pythagorean theorem can only be used on right triangles and explains how it is used. Gives several examples using the Pythagorean theorem to find the unknown side of a right triangle....

The video tutorial lesson [3:00] demonstrates the solving the width of a rectangular carpet by using the Pythagorean theorem, given the length and the diagonal of the rectangle.

The last video in a three-part series on the Binomial Theorem from the Khan Academy. This segment illustrates how the Binomial Theorem is directly related to combinatorics using (a + b)^3 as an example. Students can clearly see how a...
