Addition and Subtraction- 2 - Free MCQ Practice Test with solutions,

The correct answer is A: 8894

• Add the hundreds: 200 + 600 = 800
• Add the thousands: 3000 + 5000 = 8000
• Combine all sums: 4 + 9 + 800 + 8000 = 8894

To solve 21587 - 10479:

• Start with the units place: 7 - 9. Since 7 < 9, borrow 1 from the tens place, making it 17 - 9 = 8.
• Move to the tens place: 7 (after borrowing) - 7 = 0.
• Hundreds place: 5 - 4 = 1.
• Thousands place: 1 - 0 = 1.
• Ten-thousands place: 2 - 1 = 1.

Therefore, 21587 - 10479 = 11108, which matches option A.
