Depends on what you mean by “everything” but the answer is probably no. Besides, the major system is just a translation system… memory palaces will do the heavy lifting for you. As far as your numbers with odd number of digits, prepend zeros.
0100 or 000100 are as much a “one hundred” as 100 is; however, you can’t append a zero to it because that changes the value to “one thousand” which is different from 100.
You can use your 00-99 and bridge the gap via braille… have a look here for more details…
