Subtract hundreds
On this page children practise subtracting full hundreds by working with the hundreds digit only — for example 900 − 300 = 6 hundreds = 600. Start with the short method and the examples, then use the online practice or print a worksheet with answers.
How to solve this
- Subtracting hundreds: focus on the hundreds digits only, then attach "00": 800 − 300 = 5 hundreds = 500.
- If the hundreds don't reduce to a simple fact, write it as a normal subtraction of the leading digits.
- Check by adding: 500 + 300 must give back 800.
Examples
800 − 300 = ?
500
900 − 400 = ?
500
