I have an IPython notebook and I would like to use one of my variables inside a markup cell. Is this even possible? If so, how do you do it?

Surprisingly, Jupyter Notebooks do not support the inclusion of variables in Markdown Cells out of the box. If you still use Jupyter Notebooks there is a readily solution: the Python Markdown extension. It is part of the nbextensions package which is easy to install and configure.
The idea is pretty simple, Markdown has a concept of reference links or reference-style links that allows us to define a value to a reference variable and then refer to that value later in the same document.
Both ! and % allow you to run shell commands from a Jupyter notebook. % is provided by the IPython kernel and allows you to run "magic commands", many of which include well-known shell commands. ! , provided by Jupyter, allows shell commands to be run within cells.
If you don't mind a code cell that does the job, there is a possibility without adding any extensions.
from IPython.display import Markdown as md fr=2 #GHz md("$f_r = %i$ GHz"%(fr)) This will show a markdown cell in a nicely LaTeX formatted output
