Addition without regrouping
Adding numbers in columns starting from the ones place without needing to carry over any digits.
Addition with regrouping (Carrying over)
When the sum in a column is 10 or more, we write the ones digit and carry over the tens digit to the next column.
Subtraction without regrouping
Subtracting smaller numbers from larger numbers column by column starting from the ones place without borrowing.
Subtraction with regrouping (Borrowing)
When the top digit is smaller than the bottom digit, we borrow 1 from the neighboring column to make subtraction possible.
Mental Math shortcuts
Adding or subtracting numbers quickly by breaking them into tens and ones or using numbers like 10 and 100.

Frequently Asked Questions
How do I know whether to add or subtract in word problems?
If the question asks for a total, combined amount, or 'how much together', you add. If it asks 'how much is left', 'what is the difference', or 'how many more', you subtract.
What is 'borrowing' in subtraction?
Borrowing is taking 1 from the neighboring tens place when the top digit in the ones place is too small to subtract from.
Why do we always start adding or subtracting from the ones place?
We start from the ones place so that if our answer goes over 9, we can easily carry over the extra tens to the tens column.
