Level 3

Add and subtract four digit numbers I

Lesson

Remember how you learned a variety of ways to add and subtract 3 digit numbers? You can use these same methods to add and subtract 4 digit (and even larger) numbers, too. Watch the videos below to see what this looks like.

Add 4 digit numbers

Remember!

You can add in any order.
Be sure to add numbers of the same place value.
If a place value has a sum larger than 9, regroup and carry over to the next place value (Go to the lesson on regrouping to see more).

Subtract 4 digit numbers

Remember!

In subtraction, order matters. Subtract the second number from the first.
Subtract numbers of the same place value.
If you see a smaller number being subtracted from a larger one, regroup and borrow from a larger place value. (Go to the lesson on regrouping to see more).

Worked Examples

Question 1

Find the value of $2652+5116$2652+5116.

Question 2
