I'm seeking clarity as I 2nd guess myself 😉

Using UEB, how would you braille the equation in the attached picture with the fraction numerator being a negative number?

In your print equation (y equals the fraction "negative 1 over 3" x-squared minus 2x minus 3), since the fraction includes something other than "digits, decimal points, commas or separator spaces" (GTM 6.1), it cannot be a "simple numeric fraction." So, for this fraction in which the numerator and denominator are on different levels in print, we must use the general fraction indicators and general fraction line. I would transcribe the whole equation as follows.

Thank you for the question!

Thank you, Kyle!

Oh ... just noticed ... wouldn't a grade 1 indicator be needed in front of the opening fraction indicator?

#34851

Yes, indeed! Well spotted.

Hi Kyle,

I have a similar question, a negative fraction a/b. This is what I think:

;;"-(A./B)

Thanks, Fred

Fred, that is exactly what I would do for the general fraction: minus "a over b"
