Look here.
http://www.sagemath.org/
I just looked a little.
It looks good.
It's free.
You can make worksheets online.
Click where it says, "Try Sage Online".
It will ask you for a user name and a password.
Then, immediately you can make a new worksheet.
Once you get the worksheet, trying typing, "2^2^2^2^2", or, "factorial(8000)", in the box.
Then, click on, "evaluate".
I think you can save worksheets online too.
