I am trying to create a 2 column math worksheet with the problems numbered horizontally.

The code is show below. The error is causing the enumeration (using numbers rather than letters) to render improperly:

(tsk[1]) instead of (1)

In the right column, the enumeration is rendered (tsk[1-]).

I'm working in overleaf.com. So I assume all packages are current.

A massive thanks for your able assistance! Haven't found answer on my own.

Note: Because I'm a newby, there may be extra packages in the preamble that aren't needed.

  • Your code results in an error message. In such cases, do not look at the outpu, since even if you get something that on first glance resembles a pdf file, there can still be issues with it. After an error, TeX only tries to recover enough to syntax check more of the file, it does not try to make sensible output after an error. – leandriis Mar 6 at 22:41
  • Now to your error message " Double superscript." This refers to {(m^2y^n^4)^0} in task 5. Even if code like x^2 works, I'd encourage you to enclose the superscript in a set of {} as follows: x^{2} to prevent this type of error message. – leandriis Mar 6 at 22:44
  • Now to the numbering problem: This can be reproduced by an example document as small as: \documentclass[12pt]{exam} \usepackage{tasks} \settasks{counter-format=(tsk[1]) } \begin{document} \begin{tasks}(2) \task $-12v^3$ \end{tasks} \end{document}. According to the warning, counter-format is deprecated and should be replaced with the label option. – leandriis Mar 6 at 22:49

Instead of the deprecated (since version 1.0) counter-format option use the label option and the new syntax as shown in the following, further minimalized example.

To make your actual document compilable, you will also have to get rid of the Double superscript error messages caused by \task $\frac{m^{-4}n^4\cdot(mn^2)\strut^{-3}}{(m^2y^n^4)^0}$. I'd also encourage you to always enclose sub- and superscripts into a set of {} as for example in x^{2}.

  • I copy/posted the \settasks code you provided above. Perfect fix @leandriis ! Also, thanks for reminding me to read the error logs & not to trust the rendering only. Your code revision eliminated Package tasks warning: width of the item indent {set to 2em} is too small. Error 2: Underfull \hbox (badness 10000) still remains, although doc renders perfectly -- thanks to you! Any ideas! – WyoWindStorm Mar 8 at 6:42
  • @WyoWindStorm: The message you quoted is a warning, not an error. It seems to be related to the boxes you used but I am currently not sure how to get rid of them as well. If these warning bother you, I'd suggest that you ask a follow up question specifically about them. – leandriis Mar 8 at 9:42
