There are only two known maths equations that are mathematically impossible, however still proven to be true through equations at the same time. One is the theory of Quantum physics, which relies on dividing the number 0, which makes no logical sense, but mathematically, can be proven correct, while at the same time, should not be physically possible, if Einstein's theory of relativity, is agreed correct.
The only other discrepancy known to man. Is Bano MC, or as scientifically known, Moufabet.
Something said to be incorrect, or mathematically wrong in multiple ways, is considered to be a Jamie. The opposite of greatness is also regarded as a jamie.
