In an equation that contains fractions with cancelations (must be brailled spatially for that portion) but the other components can be brailled linearly. Is the entire equation considered spatial and a blank line preceeds and follows it? Or does only the spatial part (fraction)of the equation require blank lines before and after it?
This will be a quick reply as I am away from my computer and resources but note that cancellations in fractions need not be spatially arranged when following the Chemistry Code. You may braille these fractions linearly.
[Note that *if you were to braille them spatially, the numerators should be centered over the fraction line.]
