### MATHEMATICAL DOUBLE-STRUCK DIGITS & LETTERS

Hello friends,
I have a problem and need your help.
I use your template Latex: Masters/Doctoral Thesis.
https://www.overleaf.com/latex/template ... zrzktcbzfl

It work almost perfect with me, but today I found an error and don't know how to fix.
I want to type some Mathematical double-struck digits and letters, such as 1, 2, 3... a, b, c... A, B, C...
in the following link: http://milde.users.sourceforge.net/LUCR ... ymbols.pdf
I try to use package \bbold but it doesn't really work well.

If you try with $\mathbb{ABCDEFGHIJKLMNOPQRSTUVWXYZ}$, it absolutely works.
But I want to use with the numbers and other letter but it doesn't work.
$\mathbb{1234567890qwertyuiopasdfghjklzxcvbnm}$

The smart way: Calm down and take a deep breath, read posts and provided links attentively, try to understand and ask if necessary.

Thank for your response but this doesn't work.
If I create a new script, it works. However, there is a issue in the above template and I want to fix that. Because many documents of mine depend on it. I don't know why it doesn't work, I've tried many ways like \usepackage{bbm,dsfont}.

The default math font the template uses is palatino. Remove package mathpazo, which does not support blackboard fonts in that way.
\documentclass{article}%\usepackage{mathpazo}\usepackage{bbold}\begin{document}$\mathbb{123456789}$$\mathbb{abcdef}$\end{document}
