Example 1: Multiplying a Binomial by a Binomial, Algebra I
There are particular ways to multiply binomials. One could use the FOIL method or employ the distributive property. Sal walks through each step of the FOIL method and then shows that using distribution results in the same answer. This is...

Solving Equations with the Distributive Property, Linear Equations, Algebra I
Here is an equation in which the first step is to use the distributive property to remove the parenthesis. Then, it is solved for the variables. Since variables are on both sides of the equation, it is important to verify the answer by...
Khan Academy
Recognizing Linear Functions, Linear Equations and Functions
Starting with a set of values for the x and y variables, this video shows how to tell whether these points determine a linear or non-linear function. Sal first defines linear functions in terms of the change in y over the change in x,...
Khan Academy
Rounding Whole Numbers 2, Arithmetic Properties, Pre-Algebra
This is the second in a series of three Khan Academy videos on rounding whole numbers. Students watch Sal Khan round the number 423,275 to the nearest thousand by looking at the number in the hundreds place. If it is five or higher, you...
