    Do you mean $\bigodot$ and $\bigoplus$?

Probably you need this:

\documentclass{article}
\begin{document}
$\bigodot$ \quad $\bigoplus$ \quad $\bigotimes$
\end{document}

enter image description here

amssymb gives some variants:

\documentclass{article}
\usepackage{amssymb}
\begin{document}    
$\odot$ \quad $\oplus$ \quad $\otimes$ \quad $\ominus$ \quad $\oslash$
\end{document}

enter image description here

    If you're reading this, do you know how to invert the colors? Like, a white + sign in a black circle...

    The drawback is that the "plus" or "minus" is in contact with the circle, which does not look always appropriate. For a small minus, there is \circleddash (U+229D ⊝). Sep 4, 2020 at 12:03

    Note that if you're writing equations, for instance using the align block, it's important to use odot, oplus, ominus and not the bigo versions, unless you want ugly looking equations.
