So, once upon a time, I was just doing my homework. I was lazy, and I was like, "Ugh, this is SO boring. I wish I had a calculator." And then I was like, "Say, I should MAKE one!" Now, I could've used a online calculator, but that would be boring and lazy. So I made my own! :D
If you try and add letters and symbols, you'll just get zero. Expecting much? I didn't think so.
