A good mix of Pre-Algebra problems, learners tackle everything from proportions and equations, to polygons and circles. The sections are broken up by topic with a list of the skills that are required to complete the questions. 

With endless possibilities, you can create custom flashcards to take to class as easy as 1, 2, 3! Let this flashcard creator do the work for you, just chose the level of difficulty, add or subtract, and the number of place values. Each...

Sal offers an example showing how to manipulate numbers on either side of the equal sign to isolate the variable and solve the equation.

Sal illustrates more involved equations in this last video in a series. It follows "Simple Equations" and "Equations 2". He continues to use color-coded markings to help increase student understanding of a more complicated equation:...

"Equations 2" is the second video in this series. It follows the presentation titled "Simple Equations." This presentation shows how to solve slightly more complicated algebraic equations, like Ax+B=C. Sal uses visuals (like a number...

This is a lesson in solving linear equations. More specifically, students will see how to solve an equation with a variable expression in the denominator of a fraction.

Given two points on a line, find the value for slope using the rise over run formula. Then find the y-intercept by plugging one of the point values into the equation of a line. Finally, put these values into the equation of a line y =...

Sal offers an example showing how to manipulate numbers on either side of the equal sign to isolate the variable and solve the equation.

Sal demonstrates how to solve an equation. He begins by saying that the variable needs to be isolated. He shows how to move numbers on either side of the equal sign to isolate the variable. He also shows how to verify answers by plugging...

Basic algebraic equations of the form Ax=B are dissected. Sal encourages viewers to fully understand what the equations represent prior to learning how to manipulate them. Furthermore, he teaches students how to solve the equations...

Using a specific example, Sal shows how to find the equation of a tangent line to a given function at a specific point. Specifically, he solves the problem of finding the tangent line to the function f(x) = xex at x = 1. This problem...

Most of your students probably think a car or college is the first big expense their parents could help them with, but as it turns out these kids have been costing their parents for their whole lives. Have they ever considered how much...

Seven real-life math problems require the solving of simultaneous pairs of linear equations. Although a similar approach is taken for most of the problems, the topic of sports stadium concessions should keep the interest level high. As a...

A thorough and professional appearance characterizes a instructional activity on linear equations. Maturing mathematicians are taught to identify and exemplify linear equations with a single variable. They also classify equations...

Sal is plotting away in this video - but don't worry, it's nothing suspicious. He introduces linear equations, taking viewers through a few simple examples before applying the knowledge to word problems that are more complicated.

This lecture continues reviewing linear equations and slope problems with several example problems. Those who didn't grasp the concepts during class might find this lesson helpful.

The most helpful part of this video is at the very end, when Sal demonstrates how to solve a combinations problem incorrectly (after initially finding the correct answer). The trial-and-error strategy of solving multiple-choice math...
