Question About Texas Instruments Calculator ti-25 stat
How many different numbers can be stored, and how ?...

I mainly just want to know how the memory works. This is probably similar to many different TI calculators. The STO and RCL keys seem to refer only to a single stored number, yet many of the function keys refer to two or more arguments. I picked up this nice compact solar-battery scientific calculator at an estate sale. Since I am a computer programmer who is more familiar with HP calculators, I could probably figure out most of the operations if I only knew how to store and retrieve multiple arguments, which is probably more or less the same over a wide range or TI and other calculators. I see that there is an EXC (exchange, I guess) key, but no ENTER key. I would appreciate any suggestions.

0 On TI's the "Equal" key is the enter key. I think it was Polish notation. (Or was that HP's?) For example the format for 2 + 3 = 5 is to hit the 2 key, the + key, the 3 key, then the Equal key.
