Hello, I am a freshman at The National Autonomous University of Mexico (UNAM).

My interests are contest problems,elementary number theory, combinatorics, graph theory, linear algebra, group theory, abstract algebra and I have been meaning to learn category theory and matroids.

comment Odd Integers in Different Bases
I think you mean the number itself is odd. Since a number being odd means it is not divisible by $2$. Which does not depend in the base it is written.
