Hey there,

im completely new to sage and so far i got along quite well, but i can't figure this one out. I want to create randomized mathproblems and i want latex to decide what to print depending on calculations in sage.

So here is a functional minimal example:

\documentclass{article}
\usepackage{sagetex}
\begin{document}
    \begin{sagesilent}
        a = ZZ.random_element(1,20)
        b = ZZ.random_element(1,20)
    \end{sagesilent}
    $\sage{a}-\sage{b}$
\end{document}

What do i need to do if i want to switch a and b depending on if the result is negative or not?

As a workaround, one could do the following:

\documentclass{article}
\usepackage{sagetex}
\begin{document}
    \begin{sagesilent}
        a = ZZ.random_element(1,20)
        b = ZZ.random_element(1,20)
        if a < b:
            a, b = b, a
    \end{sagesilent}
    $\sage{a}-\sage{b}$
\end{document}

Thanks for your answer. I already got to that workaround myself in the meantime.

So the bottom line for this kind of problem is:

Do all the logic in python right? :)

Given the choice of programming in Python or in LaTeX, I know which one I'll choose. : )

In fact, there is no need to switch a and b. You can simply write $\sage{max(a,b)}-\sage{min(a,b)}$ .
