Instead of discussing boring things like whether maths were discovered or invented, tell me something cool about maths
There are so many mathematics that I'm unaware of, tell me something
@vaporeon_ oh let me teach you an obscure determinant fact I discovered a couple years ago
@vaporeon_ consider matrices that I call "checkerboard matrices". That is, if an element is in the rth row, cth column, and r + c is an even number, then the element is zero
The nonzero elements can be any number you want
Here are two examples:

@vaporeon_ if you take the determinant of a checkerboard matrix, where the matrix is n x n and n is an odd number, the determinant is always zero!
@cam @vaporeon_ strange, my friends are always telling me that....
@wallhackio @vaporeon_ in the matrix they have 4 youtubes
