Subtracting 3-Digit Numbers without Regrouping

Practice subtracting hundreds, tens, and ones

Math - Grade 2-3

Instructions: Read each problem carefully. Subtract the ones, then the tens, then the hundreds. Show your work in the space provided.
  1. 1

    Solve: 482 - 251 = ?

    Start with the ones place: 2 - 1.

    482 - 251 = 231. Subtract the ones, tens, and hundreds to get 231.
  2. 2

    Solve: 736 - 214 = ?

    736 - 214 = 522. The difference is 522.
  3. 3

    Solve: 965 - 432 = ?

    Line up the hundreds, tens, and ones before subtracting.

    965 - 432 = 533. Subtract each place value to get 533.
  4. 4

    A library had 578 books on a shelf. Students checked out 326 books. How many books are left on the shelf?

    There are 252 books left on the shelf because 578 - 326 = 252.
  5. 5

    Solve: 849 - 617 = ?

    Check that each top digit is bigger than or equal to the digit below it.

    849 - 617 = 232. The difference is 232.
  6. 6

    Solve: 693 - 172 = ?

    693 - 172 = 521. Subtracting by place value gives 521.
  7. 7

    There were 764 stickers in a box. Mia used 231 stickers for a project. How many stickers are still in the box?

    Subtract 1 from 4 in the ones place first.

    There are 533 stickers still in the box because 764 - 231 = 533.
  8. 8

    Solve: 528 - 304 = ?

    528 - 304 = 224. The answer is 224.
  9. 9

    Solve: 887 - 465 = ?

    Subtract the ones place, then the tens place, then the hundreds place.

    887 - 465 = 422. The difference is 422.
  10. 10

    A school collected 956 cans for recycling. The third grade collected 423 of them. How many cans were collected by the other grades?

    The other grades collected 533 cans because 956 - 423 = 533.
  11. 11

    Solve: 674 - 352 = ?

    In the tens place, subtract 5 tens from 7 tens.

    674 - 352 = 322. Subtract each place to get 322.
  12. 12

    Solve: 399 - 158 = ?

    399 - 158 = 241. The answer is 241.
  13. 13

    Use place value to solve: 745 - 123 = ? Write the hundreds, tens, and ones you subtract.

    Think of 745 as 7 hundreds, 4 tens, and 5 ones.

    745 - 123 = 622. You subtract 1 hundred from 7 hundreds, 2 tens from 4 tens, and 3 ones from 5 ones.
  14. 14

    A farmer picked 689 apples. She sold 246 apples. How many apples does she have left?

    The farmer has 443 apples left because 689 - 246 = 443.
  15. 15

    Solve: 853 - 521 = ? Then explain how you know no regrouping is needed.

    Compare the top digit and bottom digit in each place value column.

    853 - 521 = 332. No regrouping is needed because 3 is greater than or equal to 1, 5 is greater than or equal to 2, and 8 is greater than or equal to 5 in each place.
