| , || , ||| , |V , V , VI , V|| , V||| , |X , X
we will use these to get all other numbers :
Add X before all these to get 11 to 20
Add XX before all these to get 21 to 30
Add XXL before all these to get 31 to 39 and 40 will be XL
Add XL before all these to get 41 to 39 and 50 will be L
Add L before all these to get 51 to 60
Add LX before all these to get 61 to 70
Add LXX before all these to get 71 to 80
Add XXC before all these to get 81 to 89 and 90 would be XC
