I need to type math symbols. How do I do that?

That backwards L is the fraction symbol. The FX9750 GII does nor have the Math display.

abs(-3)='-3' =3
The symbol is ' '

What model and ram is your pc???
what programs have issues... names??
what is your os??

Here you go, Ray Ray...

In order to calculate the factorial of a number you must do the following:

1. Type your number [8]
2. Hit MATH
3. Scroll to PRB
4. Hit ENTER [The factorial symbol should be either the 1st one on that list or the 4th one]


Longstoryshort, if you want to find the factorial symbol on your TI-83 you must go to MATH. PRB. !. Done


By the way...that factorial is the fastest growing type of function in mathematics, and it is the backbone behind permutation, combinations, and a lot of probability theory.

most common way for software to show exponentiation is with a double asterisk
ie; 9 to the 10th power would be 9**10

Don't recommend PCL6 for this copier. Try latest PCL5e and PS.
If that doesn't work get tech to come out and load latest firmware and see if it works.

.76 and there should be a little triangle top symbol like /\ that you can put next to it like .76/\17 but the /\ will be a lot smaller than i just typed. you will see it on you calculator

Which version of Microsoft Word are you using? Older versions use Equation Editor. If you did not install it, you can do so from the installation disc. If you are using Word 2007, typing math equations is already ready to go from the Ribbon.

A fraction is just division of the numerator by the denominator.  So all you have to do is enter the division symbol in place of the fraction bar.  If you are trying to enter a mixed fraction: for example 3 3/5 enter: (3+3/5) were the / is the division button or your calculator.

You can enter any root by typing the number, then hitting MATH and 5, which brings up the root symbol with the x in front of it: x√. So the fifth-root would be 5 -> MATH -> 5 and then whatever number you want to get the fifth-root for: 5x√10 for example. As someone else had mentioned, you can also raise it to a rational power: 3^(1/3) which would be the same as the cubed root of 3, but you could also type: 3 -> MATH -> 5 -> 3 and get the same answer, but looking like this in your calculator: 3x√3. The option for 4 actually is a predefined cubed-root, and the one for option 5 there is the root symbol that can be used with any number before it to get any root you want. There are no parenthesis as you get when using the predefined square-root and cubed-root functions, though, so you may want to type them in yourself if entering a long string of operations in the calculator at one time to make sure the calculator doesn't include numbers under the root that you don't want it to. But I guess it depends on preference in terms of what method you choose between the rational exponents or the root symbol (and most would go with whichever seems easiest and quickest to enter), but you asked specifically how to get the cubed-root on the TI-83 Plus, so there's my best attempt at answering your question.
