In this video lesson we will learn the rules for adding rational numbers. We will apply the rules we have learned for adding integers. When adding the same signed rational values, we will add the absolute values and keep the sign. When...

Lets have a discussion about a powerful and semi-confusing programming topic - variables.



A variable is like a bucket. You choose what types of stuff you want in the bucket and can change the contents...

In this video lesson we will learn that we use the same rule for subtracting rational numbers as we did for subtracting integers. We will rewrite the subtraction problem to be an addition problem by adding the opposite value. Fondly...

In this video lesson we will learn the steps to solving a two step algebraic equation. We will first learn how to represent the equation with algebra tiles. Then, we will model how to solve the equation using algebra tiles by creating...

In this video lesson, we will continue to use the Five Step process to solving a linear equation. Equations in this lesson will have variables on both sides. Equations will require using the distributive property, combining like terms,...

In this video, we look at an example of calculating the final price of a computer that was on sale for 30% off, with an additional 15% discount from a coupon and a 7.25% tax rate. The teacher emphasizes the importance of understanding...
