Hey /sci/ I got a question for you. Im reading a textbook on digital design and Ive ran into a strange boolean equation that has the same output for the function and the complement. The function is W•X + Y•Z and its inverse would be W`+ X` • Y` + Z`. For the input WXYZ = 1110 they both give 1. Whats going on here?

>(W`+ X`) • (Y` + Z`)

Neither W`+ X` or Y` + Z` are 1 when WXYZ = 1110, so W`+ X` • Y` + Z` = 0.

Or the other way around if I'm misreading your weird notation.
