Subtracting Decimals

Published on

Subtracting decimal numbers is just like subtracting whole numbers, but with a little extra attention to the decimal point.

The decimal point separates the whole part of a number from the parts smaller than one. When you subtract decimal numbers, it's important to line up the decimal points so that you are subtracting the numbers in the same place value.

For example, let's say you want to subtract 1.6 from 2.5. You would start by writing down the numbers with the decimal point lined up:

2.5

1.6 Next, you would subtract the numbers just like you would with whole numbers, starting from the right-most column and working your way left.

2.5

1.6 0.9

The answer is 0.9, and you can see that the decimal point stays in the same place as in the original numbers.

It's important to be careful when subtracting decimal numbers and to always line up the decimal points. With a little practice, you'll be subtracting decimal numbers like a pro!
