The beauty of math; the humor of stupidity.

There’s an image going around that purports to explain the origin of the arabic numerals. It’s cute. It claims to show why the numerals that we use look the way that they do. Here it is…

varpi and lemniscates

if n0,n_1 have the same parity (both odd or both even), then winner is: max{n0,n1}

else, if n0,n_1 have different parity, then the winner is: min{n0,n1}

What if not only could you divide by zero, but you could understand the rest of math better because of it? Come here if you want to learn the truth!

In Mathematics, more than any other field of study, have we heard proclamations and statements similar to, "The Negro is incapable of succeeding." Ancient and present achievements contradict such statements. One of the purposes of this website is to exhibit the inaccuracy of those proclamations by exhibiting the accomplishments of the peoples of Africa and the African Diaspora within the Mathematical Sciences.
