Firstly, AkshajK is awesome, and is editing this.

What is $\frac{(x+y)(2x-y)(y-x)^{2}}{(x-y)(x^{2}-y^{2})(2x-y)} ???$

$x$ $x$ What is $\frac{(x+y)(2x-y)(y-x)^{2}}{(x-y)(x^{2}-y^{2})(2x-y)} ???$ oh.. donnoo

Test 6

NeoMathematicalKid was here. And he broke the line of asy diagrams.

$\begin{align*}\sum^4_{k=1}\left(\sum^k_{j=1}kj\right)&=\sum^4_{k=1}\left(k\sum^k_{j=1}j\right)\\ &=\sum^4_{k=1}\left(k(1+2+\cdots +k)\right)\\ &=\sum^4_{k=1}(k+2k+\cdots +k^2)\\ &=(1)+(2+4)+(3+6+9)+(4+8+12+16)\\ &=1+6+18+40\\ &=\boxed{65} \end{align*}$ (Error compiling LaTeX. Unknown error_msg)

What is $\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{e^{1\pi}}}}}}+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{1+\cfrac{1}{20}}}}}}$ ?!?! I got carried away.
