0,1,4,7 Keys acting up. I have a ti-83 and

first of all i would give a factory reset a try, if you press 2nd then the + button then scroll down to reset and do a full factory reset, that might fix your problem if it's software based, which would be my guess since it happened after you did something.

Large factorials ti84

The TI-84 is limited to numbers with at most twelve significant digits.

If you must know the EXACT value of 16!, try this. Calculate 14!. Note the two zeroes at the end. Strip them off by dividing by 100 and remember the two zeroes. Multiply by 15. Strip off the last zero by dividing by 10 and remember that we've now stripped off three zeroes. Multiply by 16. Add the three zeroes at the end to get a fourteen-digit number.

In this particular case the result is exactly what you get by using the FACT function. That's also true for 17!, but it breaks down past that because 18! has more than twelve significant digits.

The whole point of the calculator is to allow you to do calculations with a reasonable degree of accuracy, as opposed to exactly. You'll notice that it can't do a simple operation like dividing 1 by 3 and produce an EXACT answer---only a twelve-digit approximation.

How do you solve 7!-5!?

First of all, you are not trying to solve. You are trying to calculate.
If your calculator is a scientific calculator, you must have a key for the factorial function. It should be marked n! or x!.
Enter the number whose factorial you want then press the [n!] key.
7[n!] [-] 5 [n!] =
The esult should be 4920
On graphing calculators look for the factorial function under a Prob(ability) menu

I own a old TI-82 graphing calculaor and i was wondering where the +/- button was because i need to figureout an equation with a negitive in it and i cant find the button!!!!

Well, there are 2 ways, the easy way and the hard way, and I will give both.

EASY: the [+/-] button should be near the [ENTER] button
"HARD": type in "0" and then subtract the number that you want negatave and "FixYa!"
P.S. If this solved your problem please rate it as best answer.
