Multiplicative inverses. That's a mouthful! Really, this term just refers to numbers that when multiplied together equal 1. These numbers are also called reciprocals of each other! Learn about multiplicative inverses by watching this tutorial.
The distributive property is a very deep math principle that helps make math work. It's the rule that lets you expand parentheses, and so it's really critical to understand if you want to get good at simplifying expressions. So check out the tutorial and let us know what you think!
We know that calculators are everywhere, but that doesn't mean that long division isn't important! Sometimes you won't be allowed to use a calculator, and when those times occur, you'll be thankful that you watched this video!
Subtracting fractions with unlike denominators doesn't have to be a nightmare. Just find a common denominator and everything calms down! See how to keep your fraction subtraction calm with this tutorial.
Subtracting fractions with like denominators? Just subtract the numerators and put the result over the common denominator! To see this process in action, check out this tutorial!
A positive times a positive is a positive. A negative times a negative is a positive. What about a negative times a positive? This tutorial gives you the answer by showing you how multiply (and divide!) with mixed signs.
Working with fractions can be intimidating, but if you arm yourself with the right tools, you'll find that working with fractions is no harder than working with basic numbers. In this tutorial you'll see the process for multiplying 3 very simple fractions. Enjoy!
Trying to add fractions with unlike denominators? You're going to need a common denominator first! Follow along with this tutorial and see what you need to do to add these fractions together.
How do you combine a positive and a negative number? This tutorial shows you how. You even get to see it explained with a number line!
Multiplying a whole number and a fraction can be confusing, but this tutorial helps to sort things out. Check it out!
Multiplying and dividing numbers takes a good amount of thinking, and it's easy to make a mistake. But you can make sure that you're on the right track if you check whether the answer should be positive or negative. In this tutorial you'll see exactly how to tell if your answer will be positive or negative, even if you don't know the exact value of the answer. That way you'll always be able to check your answers!
While adding fractions can be hard, adding fractions with the same denominator is just as easy as adding numbers. That's why when you add fractions you first get all of them to have the same denominator, and then add them up. In this tutorial you get to see just how easy it is to add up fractions once they have the same denominator!
Subtracting a positive from a negative? Just remember: subtracting a positive is the same as adding a negative. See how it works in this tutorial!
Subtracting a negative from a positive? Just remember: subtracting a negative is the same as adding a positive. See how it works in this tutorial!
There are lots of different kind of numbers that you should know about, and that includes rational numbers. Check out the tutorial!
Complex fractions are, well, complex. But if you watch this tutorial, you'll see how to make these complex fractions much simpler!
Ever wondered what makes complex fractions so complex? Check out this video tutorial and wonder no more :)
When you divide fractions, the trick is to rewrite division as a multiplication. But the truth is that you can always rewrite division as a multiplication, and in this tutorial you'll see the rule that makes that possible!
Complex fractions can be pretty complex. Luckily, you can simplify a complex fraction to make it much easier to work with. See how in this tutorial!
Reciprocals are important when it comes to dividing fractions, finding perpendicular lines, dealing with inverse proportions, and so much more! In this tutorial you can review the basics about reciprocals.
Some problems require adding and subtracting a combination of positive and negative numbers. Watch this tutorial and learn how to keep everything organized so you can find the answer!
Subtracting a positive is the same thing as adding a negative. Subtracting a negative is the same as adding a positive. Get a closer look with this tutorial!
Adding two negative numbers together? Just add the absolute value of each number together, put a negative sign in front, and you have your answer! See how it's done in this tutorial.
Subtracting a whole number from a fraction can be tricky. Luckily, watching this tutorial can make this subtraction no big deal!
