Rationale: To transform an incorrect operation into a correct one, we need to adjust the digits to ensure they are within the range of single-digit numbers (1-9). This may involve moving matchsticks to change the numbers.
1. For 6-5=8, we need to move 1 matchstick from the 8 to the 6 to make it 5, resulting in 5-5=8.
2. For 549-245=1, we need to move 1 matchstick from the 9 to the 2 to make it 1, resulting in 541-145=1.
