I'm in the midst of creating introductory multiplication and division exercises, exemplified by the following, except that I would like to separate the exercises from the solutions.

I can almost do it now... but not quite.

I made the code below which compiles, but does ...

The code below compiles at sharelatex.com, but not on my desktop with Texmaker.

I opened a bunch of other files in Texmaker and all compiled normally.

What's going on?

Thanks for any help!

Wow. This is a super long and technical thread. I understand very little of it. Google searching dll files didn't help too much because it mostly gave me other technical advice that I didn't understand.

Is there an easy way to fix this? To make it just do what it's supposed to do and has been doing ...

Out of nowhere, my TeXmaker on my laptop has stopped compiling.

I got this error message, uninstalled and reinstalled TeXmaker, and got the error message again. :x

What should I do next?

I want to show a picture of the error message, but it's really hard to put images in these forums, so I'll ...

Can anybody recommend an introduction to the \ifnum commands?

I can't make sense of code that has them but I'd like to learn how they work.

Thanks!

Heh, what does that mean?

Doesn't {random(0,10)} already create a random value?

\documentclass{article}
\usepackage{tikz}
\pgfmathsetseed{\number\pdfrandomseed}
\newcommand*{\NewNumbers}{%
\pgfmathsetmacro{\A}{random(0,10)}
\pgfmathsetmacro{\B}{random(0,10)}}
\begin{document}
\NewNumbers
\A +\B = ?

\NewNumbers
\A *\B = ?
\end{document}


I think I understand most of ...

@stefan_k and @rais

Thank you for your posts! I will try to make sense of them later today.

I've been reading through the TikZ & PGF Manual Part VIII but, honestly, I can't make sense of it. The technical jargon is far beyond my current knowledge.

Is there a more non-technical introduction to random number generation that anybody knows of?

For the time being, I would like to create ...

I haven't, but I'm going to check that out.

Thanks!
