Multiplication and Division
Introduction to Multiplication
What is Multiplication?
When you multiply, you're increasing a number over and over again. Basically, multiplication is adding something more than once. For instance, if you eat 4 pieces of candy, then you eat another 4, then 4 more, you can say that you multiplied the amount of candy you ate.
Multiplication happens all the time in real life. For example, consider the situation below.
Writing Multiplication Expressions
As you just saw, a multiplication expression is written like this:
2 x 6
You can read that expression as two times six. The multiplication symbol (x) can also be called the times symbol. Remember, you always put it between the numbers you want to multiply.
Many real-life situations can be expressed with multiplication. For instance, imagine that you want to make three cakes. The recipe says that each cake will need two eggs. In other words, you need 3 x 2 eggs.
Now you try it. Write the following situations as multiplication expressions. Don't try to solve them yet.
You have six pairs of two socks each.
You need to take two pills four times a day.
Movie tickets cost $9. You buy three.
