NEW MANDELA?
Has anyone in the past few weeks remember there being another number between 8 and 9? This could be potentially groundbreaking.
I remember as a child really struggling to add or multiply with a specific number, but I can no longer recall which number it was. I have a distinct memory of my third grade teacher who was quite abusive berating me for my performance when it came to math and specifically this number.
Anyone else?

No because arabic numerals are a base-10 system. The system is defined this way because we use 10 different symbols (0-9) to represent numbers, and then repeat the use of those same ten symbols to represent progressively higher powers of 10. There is not another number between 8 and 9 because that would mean a base-11 system, and we would all notice immediately if something as fundamental as our numbering systems were off.

As  said, no. For everyday life base10 is by far the easiest to use and it's engrained far and wide in our everyday world, it would be earth shattering if we just added or removed a number.

It's also not like we couldn't make up higher digits, we literally did for the Hexadecimal system (base16). We just don't use it apart from specialty use because it's inconvenient to do for most things.
