I came across this weird formula when I was doing some machine learning stuff. The formula is
$$89 - (e^{\frac{m}{rd}}) = 64 - e(\frac{m}{rd})$$
They seem to be both equal, but I am just curious as to why. Please help. The variables are just there for placement, assuming that $m == m$, $r == r$, $d == d$. $e$ is Euler's constant. Thank you and appreciate your time.
