Tips for using it

Check each answer by adding it back to the number taken away.
Think addition: 12 - 7 asks what you add to 7 to make 12.
For small numbers, counting back on a number line is a reliable strategy.
When borrowing, cross out the digit you borrow from and write the new number above it.
