Adding and Subtracting Decimals When adding and subtracting decimals, first, line up the decimals.  We have 4.23 plus 9.075.

It is the same with subtraction. 5.629 minus 0.45.

Then, if you have any empty spaces, you can fill them in with zeroes. Adding zeroes to the back of your number, to the back of a decimal does not change the value of your number. So, these numbers are still what they were. They’re still equal.
