Here it is, in 3 easy steps (you will have to modify, because I am using a TI-83+, and I don't have a TI-85 to look at.):

1.) Press the [MATH] key
2.) "Hit" the [ENTER] key
3.) Repeat step two.

I don't know how to simplify fractions on this calculator.


You do not simplify fractions on the calculator. If the calculator is able to display fraction results, be sure that the form it gives you is the simplest. If the fraction is a mixed one there is usually a key to switch from mixed to improper, and from improper to mixed the keys are [a b/c] and [d/c]

How do u do fractions


To do fractions on the TI-83, you must use parentheses.
The parentheses buttons (there are two of them, facing either way) are near the upper right corner of the buttons on the calculator.
To write a fraction, you must enclose it in parentheses, using the divide button (the slash) as the fraction sign (the line between the numerator and the denominator)
For example, this would be one half:
(1/2)
And this would be one third:
(1/3)
As long as the numbers are confined between parentheses, with no other numbers in there besides the fraction, they will act as a single group.
Don't ever be afraid to use plenty of parentheses, either!
For example, if you wanted to add one half to one third, and then multiply it all by three, the following would definitely be acceptable:
((1/2)+(1/3))*3

How do i do fractions with this calculator? there are so many keys i dont know what to push.


The primary key to enter something that resembles a fraction is the division key, the one above the multiplication key.
However, any division you enter yields a decimal number, unless the result is an integer.

To keep the result of a division as a (reduced) fraction use the [|=>Frac] or [ToFrac] command. It is accessible by the following key sequence
[MATH][1:ToFrac].
Insert it after the fraction, before pressing the [ENTER] key to get the result.

By pressing [MATH][2:ToDec] you convert a fraction in to a decimal number.
