Frequently Asked Questions
How do I know whether to add or subtract in a word problem?
If the problem asks for a total, combined amount, or says 'altogether', you add. If it asks 'how many are left' or 'what is the difference', you subtract.
What should I do if the top number is smaller during subtraction?
You need to borrow 1 from the neighboring tens or hundreds column to make the top number bigger.
Why do we start adding from the ones column?
We always start from the ones column (right side) so we can easily carry over any extra tens to the next column.
