    has anyone composed a tn-to-be-proud-of to accompany formal proofs, specifically one that describes step numbering? willing to share it?

    Here's the one my teacher taught me in 1967.

    In formal proofs in this volume, the format showing step-numbered "Statements" and "Reasons" in two side-by-side columns has been changed. The braille shows all statements and reasons beginning at the margin and the letter S or R following the step-number.

    PS. My teacher was Helen Roberts, the original author of the Intro to Braille Mathematics. I only completed the book after she died prematurely.
