Every answer with the reasoning behind it. Worth reading after you have tried the set — or on its own, if you are a parent marking it.

  1. 3456 + 2178 = ?

    Answer: 5634

    3456 + 2178 = 5634.

  2. 8005 − 2467 = ?

    Answer: 5538

    8005 − 2467 = 5538. The two zeros in the middle both need regrouping.

  3. A shop had 1250 books. It sold 476 of them. How many books were left?

    Answer: 774

    1250 − 476 = 774.

  4. ? + 2350 = 5000

    Answer: 2650

    5000 − 2350 = 2650, so 2650 + 2350 = 5000.

  5. What must be added to 3780 to make 6000?

    Answer: 2220

    6000 − 3780 = 2220.

  6. Ali collected 2340 stamps. Bala collected 1875 more stamps than Ali. How many stamps did they collect altogether?

    Answer: 6555

    Bala has 2340 + 1875 = 4215. Altogether: 2340 + 4215 = 6555.

  7. 7000 − 3456 = ?

    Answer: 3544

    7000 − 3456 = 3544. Every column needs regrouping from the 7 thousands.

  8. There were 4512 people at a fair. 1236 people went home, then 845 more arrived. How many people were at the fair then?

    Answer: 4121

    4512 − 1236 = 3276, then 3276 + 845 = 4121.

  9. The sum of two numbers is 8400. One of them is 3650. What is the other number?

    Answer: 4750

    8400 − 3650 = 4750.
