I kinda gave up on the negatives because it took to long
Skewed Bijective Decimal is a modified bijective decimal where some digits are replaced. 0, 3, 6, and 9 have been removed and replaced with A = 10, B = 13, H = -14, and L = -1. Everything else works like any base 10, this base is really not that complex, it just adds a new way of writing numbers and there is no longer a need for a negative sign because of the new negative digits. Only the simplest notation is valid, such as LA1 is equal to 1, but 1 is the simplest notation so LA1 invalid Example of -20 to 20: L7A L81 L82 L7B L84 L85 H L87 L88 LL L8A L1 L2 L8B L4 L5 1H L7 L8 L LA 1 2 LB 4 5 2H 7 8 1L A 11 12 B 14 15 3H 17 18 2L 1A Creds to @Number17_Guy and @RodolfoYT12345 and TheGrayCuber on youtube for the idea Watch his video! https://www.youtube.com/watch?v=Bh7o_Q1O1NA
