How to do long subtraction?

Follow the below steps to find the difference of two numbers.

Step 1: Write the larger number on top and smaller number on bottom.

For example, if 234 & 435 is given

4 2 5 
2 3 4

Step 2: Write the numbers in a sequence such as the ones digits of both numbers comes in the same column, similarly, tens, hundreds, thousands, etc. 

Step 3: If there is a decimal point, it must be written after the ones digit.
For example, if 234 & 435.12 is given

4 3 5. 1 2
2 3 4. 0 0

Step 4: Start subtracting from right to left and write the answer of each difference in the bottom of the columns.

Step 5: If the upper number is smaller than the lower number, then take the carry from the left most digit.

³4  ¹²2 5 
  2     3 4
  1     9 1

Step 6: If the upper number is smaller than the lower number, calculate the result according to taking the larger number upside and smaller one on the bottom. After that write a negative sign with the result. 

For example, 123 – 430

4 ²3 0¹⁰
1   2 3
3   0 7
Hence, 123 – 430 = -307
