To calculate \( 843,219 - 532,458 \):
- Start from the rightmost digit:
- 9 - 8 = 1
- 1 - 5 = -4 (borrow 1 from the next column, making it 11 - 5 = 6)
- 2 - 4 = -2 (borrow 1 from the next column, making it 12 - 4 = 8)
- 3 - 2 = 1
- 8 - 5 = 3
- 8 - 0 = 3 (since there's no digit to subtract from)
The final result is \( 310,761 \).
So the answer is 310,761.
