In university I had to work on a project, that concerns number $3141592653589793$. Teacher told me, that since there are no zeros, I should work in $9$ based numbering system. But in $9$ based numbering system there is $0$. So is it possible to use "made up" $9$ based numbering system, which will consist from numbers from $1$ to $9$? Or is my teacher really messed up?
