Learn How to Subtract Decimals

Preview

Subtracting decimals is really easy just like the last chapter on adding decimals. All that you do is arrange the decimal points so that they match each other. Then you just simply subtract. But remember that before you do any subtraction you have to bring the decimal point straight down.

Let's say we have the decimals 5.6-4.6:

 5.6
-4.6
 1.0  OR 1!

Learning how to add decimals is as easy as 1, 2, 3's. All you need to know is that whenever you are adding decimals, you have to line up the decimal points. For example, if the two numbers are 2.50+25.7, you will line up the decimal points like this:

    2.50
+25.7
                                                   
 Always add zeros in blank spot to make it easier for you to add.

  02.50
+25.70

Now just add and bring down decimal point just as it is!

  02.50
+25.70
  28.20  OR 28.2!

To under this better I suggest you watch the video...and try some of these!
