Awesome Online Calculator

Hello fellow muggles or magical creature reading this. And if you don't know who I am, I am Joleen, a kind half-blood. :) Our amazing teachers, Natalie and Uncle Hao, taught us about a magic called code. Just recently we created a uppercase, lowercase program and a magnificent calculator. And if you learn as much as we do, maybe YOU can become a wizard or witch. By then, see you soon.
