I have the expression 3x^2 that needs to be underlined. I assume I use the 5-step rule:
First the multipurpose indicator, then the expression that needs underlining, then the Directly Under symbol, then the bar, and then the termination indicator.

My question is: Since the expression to be underlined ends in a superscript, do I use the dot 5 to bring it back to the baseline before I use the Directly Under indicator (or do I not need that dot 5 baseline indicator here)?

I will attach a file of the expression showing the parts that needs underlining. Thanks so much for your help.

It would help me to answer your question if I knew (from context) what the purpose is for the underlining. Would you be able to attach the complete page or question, rather than just the expression?
Thank you.

It turns out the underlining was used to help recognize like terms. I will attach an example in context. It uses single underlining to show one set of like terms and double underlining to show another set of like terms. I wondered how I should show this in the braille.
Thanks.

If you don’t use the baseline indicator to bring the expression back to the baseline, your braille would indicate that the underlining is at the superscript level. Your modification doesn’t end with that dot 5 — it ends only with the termination indicator.
