Examples:

Step 1a

Subtract 265 from 30

Write the numbers below the other as per the places of the digits.
\$265 - 30\$

$1a$

Explanation: Arrange the numbers acorrding to their place values.

Step 1b

Start with the digits in ones place i.e., 5 - 0 = 5.

$1b$

Explanation: Now subtract the digits from one’s place 5 - 0 and the difference is 0, below the number.

Step 1c

Subtract the digits in the tens column 6 - 3.Here the difference is 3.
Now we subtract hundredth’s place i.e.,(2 - 0 = 2)

Therefore, the difference between the two numbers is:
265 - 30 = 235

$1c$

Explanation: Now subtract the digit in ten’s place.so it will be 6 - 3 = 3.Write 3 in ten’s column. Now subtract hundredth’s place i.e., 2 - 0 = 2.

Hence, 265 - 30 = 235.
