Question

THE NUMBER THAT PRECEEDS 100 BASE 12 IS BB BASE 12??????????

Answer 1

The "numerals" in base 12 are 0...10,11 decimal but of course you can not use 10 (because that means 12 in base 12) nor 11. So people use A for 10 and B for 11. So the number before 100 (base 12) is BB base 12. Just like the number before 100 base 10 is 99 base 10
