This is a fictional numeric system that I'll use for my TRPG plays and in my world.

"Dot" = 0 | I = 1 | II = 2 | III = 3 | V = 4 | "V with strike" = 5 | "Inverted N" = 6 | "V with vertical line" = 7 | "Flipped V" = 8 | "Flipped V with strike" = 9 | + = 10 | X = 100 |

S = 1,000 | "Inverted E with +" = 10,000 (myriad) | "Inverted E with E" = 100,000,000 (myriad of myriad)
