I don't get it. Where did all the numbers come from in the New Way?

I put my programmer brain to work to reverse engineer the thought process. Here's my guess.

First, take the amount you're subtracting, and add a number to it to get to the next multiple of 5.

12 + 3 = 15

Add 5 to get to multiples of 10.

15 + 5 = 20

Add multiples of 10 to get approximately to the number.

20 + 10 = 30

Add the remainder of the difference between the current amount and the number being subtracted from.

30 + 2 = 32

Here would be the associated proof for 52-23.

23 + 2 = 25
25 + 5 = 30
30 + 20 = 50
50 + 2 = 52

2+5+20+2 = 29

now let's try 306 - 12

12 + 3 = 15
15 + 5 = 20
20 + 80 = 100
100 + 200 = 300
300 + 6 = 306

3 + 5 + 80 + 200 + 6 = 294

holy s*** it works!
