Do you want to play a little one-to-one? Learn to determine algebraically if a function is one-to-one. Work through two examples using the video as a guide. 

Turning words into numbers and symbols sounds like the art of writing an algebraic expression. Young scholars first observe a lesson presentation outlining strategies for writing expressions. They then use one of the included worksheets...

The discriminant is part of the quadratic formula. A quadratic equation can have two solutions, one solution, or no solutions. The discriminant can be used to determine how many answers a quadratic equation has. Want to know how to use...

What does it mean for two vectors to be linearly independent? The resource presents the basics of basis vectors and linear combinations. The third video in the 15-part series provides a definition of linear independence in terms of the...

No negative variables allowed! The instructor demonstrates how to apply the multiplication property of -1 to solve a multi-step equation that has a negative variable.

Use prime factorization to simplify this algebraic fraction. When the factorization is done then cancel out all values in which a value from the numerator and a value from the denominator equal 1. And what is left over is then the...

A collective groan can be heard when long division is mentioned. Here's a step-by-step demonstration of how to divide a two digit number by a one digit number, with a remainder.

So what do you do when you have to solve an equation that has a negative variable? There are a couple of ways to solve this problem. In this video, the instructor first demonstrates how to use the multiplication property of -1 to get rid...

This word problem has only one set of given numbers. How does one make a graph with only one set of numbers? Make a table to get the other set of values. Now these values make ordered pairs and can be plotted on a graph.

Teach your class how to add two algebraic fractions with different denominators. The instructor in the video describes how to find the common denominator and demonstrates how to simplify the expression. A straightforward video, this...

Multiply the given algebraic fractions. But first, reduce, reduce, reduce! It is a good rule of thumb to reduce as much as possible before multiplying. So how do you reduce rational expressions? Put the like terms together and cancel the...

You will need to pay close attention while watching this video. There are many steps and many operations to do to simplify this algebraic fraction. And if it seems hard the first time you watch it and you miss something, then watch it...

Use the least common denominator to solve rational equations with variables in the denominators of algebraic fractions. Learners can watch this video to find out how to do just this! An instructor solves 2 problems by finding the least...

Teach your class how to add two algebraic fractions with different denominators. The instructor in the video describes how to find the common denominator and demonstrates how to simplify the expression. A straightforward video, this...

You have two algebraic fractions to add together so what do you do now? You say yippee because they have a common denominator. This means that all you have to do is combine the like terms in the numerators. This would be a good segment...

Rational expressions that are in the form of fractions. Yuk! The teacher demonstrates how to subtract one rational expression from the other when the expressions have a common denominator. Combine like terms and write it in simplest form.

Check out this video and see how the instructor explains how to solve a system of equations by using the elimination method. There are several steps in solving this equation: multiplying the equation by negative one, subtracting a...

The elimination method is so called because the objective is to eliminate one of the variables to solve for the remaining variable. There is an extra step in this system of equations as the original equations are not similar enough. So...

Another look at solving systems of equations by using the elimination method. In this process, the instructor first uses the distributive property to multiply one of the equations to set it up for the elimination step. Yes, there are...

So what do you do when you have to solve an equation that has a negative variable? There are a couple of ways to solve this problem. In this video, the instructor first demonstrates how to use the multiplication property of -1 to get rid...

Two equations. Wait! They don't look like the same kind of equations. How do you solve a system of equations when one equation is linear and the other is a quadratic? Watch this video as the instructor illustrates how to use the...

Given a table of values and an algebraic expression, plug in the given values and complete the table. There are many, many uses for tables and this one provides some beginning level practice.

Word problems. Inequalities. Money. What? Does Marissa have enough money left in her bank account to go to the movies? One variable, two given amounts. Set up this inequality to determine how much Marissa needs to have in her bank...
