If you mean an exponent of ten, use the EE key located just above the 7 key. For example, to enter 2.1 times ten to the seventh, press
2 . 1 EE 7

If you mean to raise a number to a power, use the y^x key located just above the divide key. For example, to enter 2 raised to the 3, press
2 y^x 3 =

Nope, there's a download online at TI's website but it's the same as the one that comes with the calculator.

SOURCE: my texas instruments ti-30Xa doesn't turn on!

It has a solar battery. It has to be in the light, either sun light or artificial light to operate. HOWEVER, if the battery is shot, it must be replaced. Take your calculator to any radio shack store and ask them to test the battery for you. If it is no good, they will be able to replace it for a fee.

SOURCE: simplifying fractions on the TI-30XA

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)

I dont understand why I keep getting the wrong exponet in trying to figure out 1500nm divided by 10^9. the answer I get is 1.5 *10^-7 -but the answer is 1.5*10^-6. What am I doing wrong?


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 = .

Why won't my TI-30XIIS let me put a negitive in the exponet?


Make sure you use the (-) key to the right of the decimal point key for negative values, not just exponents. The - key between the multiply and add keys is for subtracting one value from another.

Can i do sigma notation on a ti-30xa calculator?


No. There are some keys on the TI-30XA that may make you think so, but they are statistical operations. For example, you can enter values using the Sigma+ key and the TI-30XA can give you the sum of the values entered, sum of the squares, mean value, standard deviation and so on.

You cannot do calculations like "Give me the sum of all integers from 1 to 100" with the TI-30XA, you'd need a far more sophisticated calculator.

Can not locate the exponet key on the calculator


It's right above the divide key, marked y^x.

Or do you mean the "Enter Exponent" key? That one's right above the 7 key, marked EE.

Where is the exponet sign at


For the exponent of ten, it's the key marked "EE" just above the digit 7. For raising a value to another, it's the y^x key just above the divide.
