Two questions:
1. I've noticed that if you type colons between commands in TI Basic, the first command is executed and then the second (following the colon) is exectued, etc. Does this save space or optimize the code in any way?
2. Also wondering if there is a way to expand the power of the 89 CAS w. arithmetic. i.e. the calculator cannot do 500! or really big numbers. Is there a way to make it work?
