If you look at add 10, subtract 9, repeat. it its just like the first one, it won't work.
If you look at add 1, add 10, repeat, it also won't work from when you are getting 6 to 15.
So if you look at Add I, add 9, repeat., it works for all.

We simplify taking into account that:
- Equal signs are added and the same sign is placed.
- Different signs are subtracted and the major sign is placed.
