# Why do the numbers on Math SE show in an ugly way when not using MathJax?

I understand the need to use MathJax which I always do but I think it is very inconvenient to keep using it when having small numbers alone in different parts of the text, If I don't use it they look very ugly and bad, for example: 123 vs $$123$$, in other websites such as stackoverflow they show normally without the need to enclose them with dollar sign
