I may be showing my age - but they had an old acronym in the early computer days: GIGO
Garbage In = Garbage Out.
If your data was crap when you began, or your equations did not work - no matter what you were doing if you tried to make 2+2 = 5 it should not work - if it did you were an idiot.
It's PC'ism, a variation of current Marxist Feminism that takes the progressive agenda and says that 2+2 = whatever the female needs it to be on any given day based soley on her whim.
GIGO.
