Arrange the numbers vertically. Subtract one’s place digits 2 – 8. We have to take borrowing from ten’s place. Here the value is now 14. subtract 14 - 8 = 6 write 6 in one’s column.

$1a$

Explanation: Start subtracting with the digit at one’s place i.e., 4 - 8 We take a borrow from ten’s place since 4 < 8. Here the value is 14 subtract 14 - 8 = 6 write the 6 in one’s column.

Step 1b

Subtract ten’s place digits 1 - 0 = 1.write 1 in ten’s column.

$1b$
