Step-by-step explanation:
Thanks for the request to answer :) I see three things off the top of my head but discovered a few more as I wrote it out. This is fun!!! Answers are in bold.
10,000,000,000 = 9,999,999,999+1 or simply explained and probably the most common answer, in base 10 math in the American English, 10 billion comes after nine billion nine hundred ninety nine million nine hundred ninety nine thousand nine hundred ninety nine.
That’s in short scale. Names of large numbers - Wikipedia. 9,999,999,999 + 1 could be called 10 Milliard in long scale, and is called such in English in some countries.
In base 1, where the only character is 9, the solution is 99,999,999,999 which is equal to 11 in base 10. This answer would also satisfy “plop another 9 in there because I’m multiplying by ten, and I started with 10x0.9” but it would not be equal to 11.
When I’m attempting to teach or determine a number expressed in base 10, that is in the quadrillion’s or quintillion’s or higher, I sometimes write out in a column:
9
999
9,999
9,999,999
9,999,999,999
9,999,999,999,999
