Have you ever wanted to quickly figure out how many touchdowns there were in a football game? You can do it if you know how to multiply by 7! Read this lesson to find out how.

## The Importance of 7

It's your favorite football team's first game! You've been watching excitedly because it's such a high scoring game, 49-28. You're worried, though, because your team is behind. Your friend calls you and asks how the game is going. You want to tell her how many touchdowns each team has scored, but you don't want to make her wait while you add and subtract all those 7 point touchdowns! Use this lesson to help you multiply by 7 to figure out football (and lots of other math) problems more quickly.

## What Is Multiplication?

Multiplication is a quick way to solve a repeated addition problem. For example, if you need to solve the problem 3+3+3+3+3+3+3=21, you could just multiply 3x7=21 since there are 7 groups of 3.

In multiplication, the x is read as 'times', and it means multiply. So you would read 3x7 as '3 times 7.' And in a multiplication sentence, the numbers you are multiplying (3 and 7 in our problem above) are called factors. Finally, the number you get when you multiply the factors, 21, is called the product.

Multiplication will be really helpful when you try to figure out how many touchdowns each team has scored. If you know that 7x4=28, you know that your team's score of 28 means that they've scored 4 touchdowns, since each touchdown is worth 7 points. Note that it does not matter which order the factors are in; you can change the order and still get the same product. In other words, 4x7 still equals 28.
