Bad maths 

This term has come from the study of fractals. To simplify, fractals and self similarity are the geometric principals that can be found throughout nature and indeed the universe as a common blueprint of growth. Things often appear aesthetically pleasing or beautiful because they are mathematically/geometrically perfect. The term 'bad maths' refers to something that is not aesthetically pleasing and out of sync with the universe.
Someone tells an awful joke and there is silence, this is 'bad maths'.

A large woman is seen in the front window of a restaurant eating alone, dribbling chicken fat down her fat fucking face 'that is bad maths'.

Boy likes girl, girl likes boy, boy gets lucky, goes home with girl, girl has penis.. the unverse is not working in an aesthetically pleasing way.. bad maths.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
