Arrange the numbers vertically. Subtract one’s place digits 3 – 6. we have to take borrowing from ten’s place. Here the value is now 13. subtract 13 - 6 = 7.write 7 in one’s column.

$1a$

Explanation: Start subtracting with the digit at one’s place i.e., 3 - 6 We take a borrow from ten’s place since 3 < 6. Here the value is 13. subtract 13 - 6 = 7. write the 7 in one’s column.

Step 1b

Subtract ten’s place digits 2 - 0 = 2.write 2 in ten’s column.

$1b$

Explanation: Move to the ten’s place i.e., 2 - 0 = 2. Write 2 in the ten’s place.
