I designed a homework for HTML/CSS/JS basics. Implement a web-based calculator! It's quite simple to write a program for an experienced programmer, but for a beginner it may take a while.
Also, there are some rules:
- all buttons are functional as a real calculator does
- single page, no links to external resources such as jQuery
- multi-browser supported is prefered.
- as precise as it looks
Do you wanna try? I have writen a version (tested in Chrome)
