Adding and Subtracting Decimals
First, you need to line up the decimals and then line up the numbers.
If there is no number to line up, you can insert a Zero (0).
Second, you have to figure out if you are adding or subtracting.
If you add, you might need to carry a number to the next column.
If you subtract, you might need to borrow a number from the next column.
