Multiplying together large numbers? No problem! In this tutorial, you'll see how to perform long multiplication to find the answer (without using a calculator!). Take a look!

There are lots of different kinds of numbers that you'll come across in algebra, and a lot of these kinds of numbers are related to each other. Before you learn how they are related, you've got to learn about them separately, and in this tutorial you'll how to define integers :)

Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts.

Combining integers? You could use a number line to help find the answer! In this tutorial, see how to use a number line to add together integers with the same sign and ones with opposite signs. Take a look!
