Say we have 444 - 286. This can be written as 2 bar 4 bar 2. So 2 bar 42 can be written as 158(all from 9 last from 10 rule). This allows you to do subtractions with having carry numbers.
Try 6767 - 1908 = 5 bar 2 6 bar 1= 4859. Try these yourself 804 - 388.

Vedic Maths Bar Numbers
This is 10 -1 or 9. Bar Numbers are very useful for subtractions. Think of them as negative numbers so 10 and -1 = 9.
So 7 bar 2 is 68. To create a bar number we substract from 10. 9 bar 1 is 89 as 89 is close to 90 bar 1. If a number has a bar number in it split the nuimber after the bar.
7 bar 3 1= 7 bar 3/ 1= 671.
We can combine bar number resolution with the sutra, All from 9 and last from 10. So 5 bar 33 means 33 subtracted from 100 = 467.
Try this yourself 7 bar 14.
