Two ways:
1) 2nd -> 0/Catalog -> 3 -> Enter
2) MATH -> ◄ -> 4
The Factorial symbol is the exclamation point. (!) This symbol means to multiply a row of natural descending numbers.
The symbol for a factorial is the exclamation point (!). For example, 4! = 4*3*2*1 = 24.
an exclamation point !
Unfourtunately, it is not possible to expand with the TI-84. Only the TI-89 can expand polynomials.
You can play Ti-84 games with the 84 keypad but I have yet to find games for the n-Spire CAS. So just download TI-84 games and use the 84 keypad.

The TI-84 is a graphing calculater. It is mostly just an update to the TI-83 calculater.

Yes, the TI-84 is allowed during the ACT.

Sorry, but no, to my knowledge there are no shells for the TI-84=CSE, and there probably will never be, the last descusions about being in 2006, and the TI-84+CSE is not compatible with the old TI-84 or even TI-84+SE programs. I am sorry to say but you will never have complicated games for this edition of the TI calculators but there are some simple games that don't need shells, such as tetris, worms etc:

there isn't an infity button on the ti-84 Texas instruments graphic calculator.
Ti - were you hoping for something else ? ;-)
You cant factor on the ti-84. however the ti-89 does do this but its almost easier to just do it in your head. Plus on the ti-89 the way you enter it in there is a very high risk for error.
