Calculator

I just joined Daily UI to keep up w/ design since I haven't been doing much of it as a Front-End Developer. Forgot what challenge this was, but when I did this, I thought of
- "What is it mostly used for?"
Quick standard math.

- "What would make a calculator easy to use?"
Need to only know the basic math symbols. And I need to know what number I typed and what math symbol I'm using. Being able to backspace and also clear.

- "Who is using it?"
Anyone with a laptop and needs a quick standard calculator. I didn't forget the students or anyone that wants to go beyond that, hence the reason why this is just 'standard'.
