Different Win7/64 Calculator?

Hi! The calculator included with Win7 is good and can do almost everything I need it to do, but I'm looking for something better. I tried here and found too many links. Is there a good calculator here? If so, what's its name? I'm looking for something general-purpose. Thank yu.

 

Go here Download Calculators And Math Tools for Windows - MajorGeeks and sort by popularity or rating and pick one from the top.

It depends on what you want to use a calculator beyond that provided by Win7.

It could be you want to solve mathematical equations: Download Microsoft Mathematics - MajorGeeks
or advanced calculus: Download Euler Math Toolbox - MajorGeeks

 

I admit that the default calculator is good enough for most of my purposes. I just want something that's more fun. BTW, I have a DOS-based 3D graphing program and used to like creating graphs.

 

TheCalcMan seems better for my purposes, as my main use of it is to calculate compression ratios, and it would be easier if I could see the whole equation, as occasionally, I forget if I added a particular number and have to restart the whole process. I also sometimes do arithmetic on hex numbers and need a dec equivalent. Can I refine the search to get this support or Win98 support?
