Introduction to Decimals

In this intro to decimals lesson, you'll get to fully understand them before adding, subtracting, multiplying, dividing, and converting them.

Decimals and money

What if you had to read this decimal out loud?

Even though we use decimals when we use money, we read them slightly differently. Instead of three point two three, or three and twenty three-hundredths, we'll say three dollars and twenty-three cents.

You could also read it like this: "three twenty three". To save time, most people leave out the decimal point when talking about money. How about $5.99? That would be five dollars and ninety-nine cents, or five ninety-nine.

Remember, these rules only work with money. They can't be used to read other decimals.
