Yes, the Position Statement—"Terminology: UEB Math/Science and UEB with Nemeth" is published on BANA's website, on a page with other BANA Position Statements and Fact Sheets! and it tells us to use the terms "UEB Math/Science" and "UEB with Nemeth."
The slash in that term does *not* indicate that either "UEB Math" or "UEB Science" should ever be used. The full term "UEB Math/Science" should be used every time.
So, a Biology textbook transcribed using only UEB symbols is in "UEB Math/Science," and a Geometry textbook using only UEB symbols is also in "UEB Math/Science."
Thank you for the question!
