Primary 2 Mathematics Quiz - Addition Subtraction (Answer Key)

Version: 1 of 5
Total Marks: 40

Section A: Mental Addition and Subtraction (Q1–5)

Q1. 245 + 30 = 275 (2 marks)
Teaching note: Add the tens only. 245 has 4 tens (40). 40 + 30 = 70, so 245 + 30 = 275.
Working: 245 + 30 = (200 + 40 + 5) + 30 = 200 + 70 + 5 = 275.

Q2. 560 − 40 = 520 (2 marks)
Teaching note: Subtract tens only. 60 − 40 = 20, so 560 − 40 = 520.
Working: 560 − 40 = (500 + 60) − 40 = 500 + 20 = 520.

Q3. 318 + 200 = 518 (2 marks)
Teaching note: Add hundreds only. 300 + 200 = 500, so 318 + 200 = 518.
Working: 318 + 200 = (300 + 10 + 8) + 200 = 500 + 10 + 8 = 518.

Q4. 704 − 300 = 404 (2 marks)
Teaching note: Subtract hundreds only. 700 − 300 = 400, so 704 − 300 = 404.
Working: 704 − 300 = (700 + 4) − 300 = 400 + 4 = 404.

Q5. 476 + 8 = 484 (2 marks)
Teaching note: Add ones only. 6 + 8 = 14, regroup 10 ones as 1 ten. 470 + 14 = 484.
Working: 476 + 8 = 476 + 4 + 4 = 480 + 4 = 484.

Tens: 6 + 8 + 1 = 15, write 5, carry 1.
Hundreds: 3 + 2 + 1 = 6.
Answer: 652.

Q7. 438 + 574 = 1012 (2 marks)
Working:

Working:

  502
- 347
-----
  155

Ones: 2 < 7, borrow from tens (0), so borrow from hundreds: 5 hundreds → 4 hundreds, tens become 10, then borrow 1 ten → 9 tens, ones become 12. 12 − 7 = 5.
Tens: 9 − 4 = 5.
Hundreds: 4 − 3 = 1.
Answer: 155.

Q9. 610 − 283 = 327 (2 marks)
Working:

  610
- 283
-----
  327

Ones: 0 < 3, borrow from tens (1 → 0, ones 10). 10 − 3 = 7.
Tens: 0 < 8, borrow from hundreds (6 → 5, tens 10). 10 − 8 = 2.
Hundreds: 5 − 2 = 3.
Answer: 327.

Q10. 256 + 479 = 735 (2 marks)
Working:

  256
+ 479
-----
  735

Tens: 9 − 6 = 3.
Hundreds: 7 − 4 = 3.
Answer: 338.

Q12. 394 + 608 = 1002 (2 marks)
