Neganumerophobia

Enkhenumerophobia is the fear of negative numbers, a branch of numerophobia. The term originates from the Greek enkhe, "under", numero, "number", and phobos, fear. Sufferers usually became afraid of it by first learning about negative numbers in school. People suffering this number phobia may believe that there's something spiritually evil about negative numbers, like if the one is working on the negative numbers, may penalize them and possibly lure them into hell. It's the reason why enkhenumerophobes may commonly fear the Satans (satanophobia) and Hell (stygiophobia).
