A FIx formatting flag is usually raised to let contributors know that an answer needs to be improved, more often than not, in terms of how equations and math calculations are written.
For example, something like this:
molar mass=mass/no. moles
molar mass= 100g/2moles = 50g/mol
can be written, using the available formatting options, like this
2x^2 - 4x = 0 => 2x(x-2) = 0
can be written as
and so on.
So, as a conclusion, when you write an answer, try to use #'s for equations, calculations, or formulas. Also, try not to have very long paragraphs, as they make the answer difficult to read.
