Frequently Asked Questions
How do I know whether to add or subtract in a word problem?
Look for keywords! Words like 'total', 'altogether', 'more', and 'sum' mean you need to add. Words like 'left', 'remain', 'less', and 'take away' mean you need to subtract.
Why do we need to borrow during subtraction?
We borrow when the top digit is smaller than the bottom digit in a column, because a smaller number cannot give away a larger number.
How can I check if my addition answer is correct?
You can check your answer by adding the numbers in reverse order (property of addition) or by subtracting one part from the total sum to see if you get the other part.
