I have attached a page from a textbook we are formatting. Please see samples in box and exercises 8-11. Are these problems to be formatted as spatial problems? Aren't horizontal lines over horizontal lines in the addition problems confusing to the student? Help?
Wow I have overworked thinking about this. I have settled on just presenting all fractions horizontal. The only ones I will present spatially are the ones that show something in the nominator and denominator such as
-- -- = --
Otherwise I will show
⅓ 4/7 ⅕
+⅓ + 2/7 +⅗

Please see attached file for translated braille version. Sorry I spent so much time talking myself through this.
