TopNewestWow how troll....

...But so true.

That is one of the reasons why I love math so much. When you do math, there are so many problems that I cannot solve, which implies that there is so much space for me to learn, to open my mind, to view all of the possibilities that comes out of solving math problems and continuously doing math. Math is such an important aspect of my life, and I plan to continue to endeavor in my great journey of math, conquering more problems in that wonderful field that Fraulein Maria is dancing in, just to find even more beautiful flowers and majestic mountains further down the hill. – Hahn Lheem · 3 years, 6 months ago
