Frequently Asked Questions
How do I know when to add or subtract in a word problem?
Look for keywords! Words like 'total', 'altogether', and 'more' mean you should add. Words like 'left', 'remain', 'less', and 'take away' mean you should subtract.
What should I do if the top number is smaller during subtraction?
You need to borrow 1 from the next column on the left (regrouping) to make the top number bigger so you can subtract easily.
Why do we always start adding or subtracting from the ones place?
We start from the ones place on the right so that if our answer goes over 9, we can easily carry it over to the tens place correctly.
