Yes it does need fixes and improvement
I have a webpage that features several calculators and many need
updating but since they are free, the updates are not often. Each
different calculator seems to be best for different areas of math.
Some allow you to use the math symbols and others do not. The
calculators are at the below address. Notice Speedcrunch is top left
side. It also has screenshots and examples.
hope this helps
