MHF4U challenge problem but we took it wayyy too far
Consider the digits 2, 0, 1, and 9. Using each digit only once, create a formula which generates all positive integers from 1 to 100. Any mathematical operator is allowed, including concatenation of digits.
- ⬛ Simple solution for 0-100
- ✅ General solution for all real integers
- ✅ General solution for all real rationals
- ✅ General solution for all complex integers
- ✅ General solution for all complex rationals
