this can only be done in Multi line calculators.

Without knowing exactly what you're doing I can't be sure, but I suspect you're entering the 10^9 as something like 1 0 EE 9 .

1 0 EE 9 gives you 10 * 10^9, which is 10^10. You should be doing this as 1 5 0 0 / 1 EE 9 = .

Make sure you have the proper angular mode set. The TI-84 can work with degrees or radians.

Press MODE to bring up the mode screen. Use the arrow keys to highlight either "Radian" or "Degree" on the third line and press ENTER. Press 2ND [QUIT] to exit the mode screen.

If this doesn't do it, please reply to this post giving an example of a calculation and the answer you're getting from the calculator.

Use them to group expressions, to override the precedence of operations. For example, if you put in

1 + 3 * 2 + 2

the calculator will give you 9, which is 1+(3*2)+2, because multiplication takes precedence over addition. If you put in ( 1 + 3 ) * ( 2 + 2) then you'll get 16 because you've overridden the precedence to do the additions first.

on the TI-30xa...

key 1

key blue division key

key (

key 3.9

key blue multiplication key

hit 2nd

hit 10^X key in yellow

key 16

key +/- grey key at bottom between . and =

key )

Finally, key =

are there any ( ) in your equasion?

if not... you can also solve individually...

Division first:

1/3.9 =

then hit 10^x key

enter 16, and press x/-

then enter.

Your answer should read 2.56410(repeating)e-17

which is .000000000000000025641056410564105641056410......etc.

Two ways:

1) hit the equal sign

2) hit 2nd and [d/c] (you can do this multiple times to see it as the most reduced improper fraction or as a mixed fraction)

If you mean using the "EE" key it's straightforward.

To enter scientific numbers, enter the number, then press EE, then the exponent value. The TI-30XA will stay in scientific display until you "clear" or turn it off. It will also switch to scientific notation if you multiply big numbers that exceed the display.

E.g. Input 3, EE, 10, X, 3, EE, 10, =, gives you the answer 9 times 10 to the power 20. Press the "square root" key and you will get back 3 times 10 to the power 10.

You can mix entries too, e.g. 3, EE, 10, X, 2, =, gives you 6 times 10 the power 10....
