Just like Splitting in addition makes addition of large numbers simpler, similarly Splitting can be applied for subtraction of large numbers.

For example:

3 6 4 2  – 2439 :

splitting 3

The above diagrams clearly explains the benefit of correct placement of “split” line, so as we can avoid the borrow.

There can be situations when splitting may require more “parts”.

For example:

3 0 1 4 5 5 – 1 4 0 8 2 8 :

splitting 4

This method can be used for subtraction of large numbers of varying lengths. Try for below:

5455 – 1723                                                      3246 – 1319

44444 – 28288                                                   666 – 293

77777777 – 28282828
