How To Add & Subtract Decimals
How To Add & Subtract Decimals
1. Line up your decimals always when adding or subtracting. This is hugely important.
2. Sometimes there are empty spaces when you line up the decimals. Put zeros where these numbers are missing. This is called annexing zeros.
3. Now add or subtract normally. If you are subtracting be sure to regroup (borrow) if necessary.
4. Finally, bring your decimal straight down. This is why lining up the decimal when you write down the problem is so important. This is also hugely important.
