Is there a way of using the latex command overline?

Is there a way to use the latex command “overline” to represent the decimal approximation of ⅓ in a card sort?

Figured out one way. I write the latex in a text editor and then paste it into the equation editor in AB. It does not seem I can type the latex right into AB. I might be missing something obvious here!

It’s because it represents backslashes with “\backslash” instead of "" which means if you typed “\pm” to make a ± sign, it would represent it internally as “\backslash pm” instead of “\pm” so instead, you can paste it from a note in Desmos (made using a quotation mark in an empty function) which uses plain text.
