In honor of today’s uniform date, a quick puzzle: using six ones along with the basic arithmetic operations and exponentiation, write expressions equal to the numbers 0 through 11.
(Before I begin, the WolframAlpha blog has 11 ways the number 1 can be used to create some interesting mathematical results. I now know, for example, that an 11-sided polygon is called a hendecagon).
Ok, I got stuck on 11, which was my original goal. I can do it with some inelegant tactics (e.g. the ++ operator from some programming languages), but I couldn’t figure out a way under my original constraints. Any thoughts? Or any other methods for getting the numbers from 0 to 10?
