# Multiplication and division

Contents

Multiplication and division are two of the most important operations to understand in math. If you drink 2 cups of water, 5 times, how much water have you drunk? If you need to divide 9 slices of cake between 3 friends, how much cake does each friend get?

Welcome to the concept of multiplication.

Let's see how multiplication and division are related.

Learn multiplication facts (sometimes called times tables).

Learn how to read a multiplication table. Can you see any patterns?

Welcome to the concept of division.

Learn about the commutative, associative, and distributive properties of multiplication. Solve multiplication problems by changing the order of factors (commutativity), the grouping of factors (associativity), and by decomposing the factors (distributive property).

As we'll see in this tutorial, multiplying a multiple of 10--like 10, 20, 30, 40, etc.--by a single digit number is not too much more complicated.

We are now going to solve real-world problems using multiple steps. Along the way, we'll be using letters to represent unknown quantities.

Math is full of patterns that will keep emerging as you explore it (this is what makes math so beautiful). We begin to just scratch the surface in this tutorial!
