Step by step solution :

	3	5	5
-	1	4	5

Step-1 : 5 - 5
Here 5 `=` 5, so directly subtract it
`=5-5`
`=0_6`

	3	5	5
-	1	4	5
			0

Step-2 : 5 - 4
Here 5 `>` 4, so directly subtract it
`=5-4`
`=1_6`

	3	5	5
-	1	4	5
		1	0

Step-3 : 3 - 1
Here 3 `>` 1, so directly subtract it
`=3-1`
`=2_6`

	3	5	5
-	1	4	5
	2	1	0

Step by step solution :

	2	5	0	0
-	0	5	5	5

Step-1 : 0 - 5
Here 0 `<` 5, we take borrow from 0, which takes borrow from 5
So 5 becomes 4, 0 becomes 5 and 0 becomes 0+6=6
`=6-5`
`=1_6`

			5
		4	6	6
	2	5	0	0
-	0	5	5	5
				1

Step-2 : 5 - 5
Here 5 `=` 5, so directly subtract it
`=5-5`
`=0_6`

			5
		4	6	6
	2	5	0	0
-	0	5	5	5
			0	1

Step-3 : 4 - 5
Here 4 `<` 5, we take borrow from 2
So 2 becomes 1 and 4 becomes 4+6=10
`=10-5`
`=5_6`

		10	5
	1	4	6	6
	2	5	0	0
-	0	5	5	5
		5	0	1

Step-4 : 1 - 0
Here 1 `>` 0, so directly subtract it
`=1-0`
`=1_6`

		10	5
	1	4	6	6
	2	5	0	0
-	0	5	5	5
	1	5	0	1

Step by step solution :

	4	3	4	3
-	0	4	5	3

Step-1 : 3 - 3
Here 3 `=` 3, so directly subtract it
`=3-3`
`=0_6`

	4	3	4	3
-	0	4	5	3
				0

Step-2 : 4 - 5
Here 4 `<` 5, we take borrow from 3
So 3 becomes 2 and 4 becomes 4+6=10
`=10-5`
`=5_6`

		2	10
	4	3	4	3
-	0	4	5	3
			5	0

Step-3 : 2 - 4
Here 2 `<` 4, we take borrow from 4
So 4 becomes 3 and 2 becomes 2+6=8
`=8-4`
`=4_6`

		8
	3	2	10
	4	3	4	3
-	0	4	5	3
		4	5	0

Step-4 : 3 - 0
Here 3 `>` 0, so directly subtract it
`=3-0`
`=3_6`

		8
	3	2	10
	4	3	4	3
-	0	4	5	3
	3	4	5	0
