But sometimes the expression is more readable with a "*", IMHO: "256 * I" vs. "256I" > Style of formula is changed to TeX's mathematical display mode. There are some braces left over from \frac. BTW, why did you replace "\frac" with "\over"? (I'm TeX/LaTeX beginner...) > Can this reformation be acceptable for all users? I wonder if we shouldn't make some more fundamental changes: It looks like layer/blend mode formulas are typically expressed using values in the range 0..1. This makes them independent of the color depth and simplifies the equations (e.g. "E = M * I" for the multiply mode). If we just want/need to explain layer modes without describing any internal details of how to compute the "real" values, we should consider switching to the - as far as I see - common way to describe layer/blend modes.
