Best symbolic interface

- This is the symbolic calculator that you will reach for on a day to day basis.
- Very clear CAS screen
- Good examples on each function.
- Very good Copy-Paste.
- Very easy on the fly choice to convert answers to numerical values.
- Great calculus tool.
- Should have an highlighted numerical keypad, to separate from functions + - / x etc.
this is the reason for 4 stars; but its well worth 5 stars for its ease of use.
