Work Step by Step

6 is less than 8, so in order to subtract we first have to regroup from the tens digit to turn 6 to 16. Then we subtract 16-8 = 8 for the ones column. Next, the 1 in the tens place turns to 0, so we have to regroup again from the hundreds digit to get 10, and we subtract 10-1 = 9 for the tens column. Finally, we subtract 8-6 = 2 for the hundreds column. From the 2 in the hundreds place, 9 in the tens place, and 8 in the ones place, we get 298.
