SOURCE: TI-30xa Calculator Reciprocal Key

It does. For instance, to get the reciprocal of 4, enter the following sequence: 4 [1/x] (this last key to be found third row down, second black key in). The decimal 0.25 will appear as the result. Convert this, if you want, to the fraction 1/4 by pressing the yellow function key [2nd], then {F<>D] located bottom, far left. Hope that's what you wanted!

If you mean the standard deviation, there are two shifted keys on the third row marked with a lower-case Greek sigma. sigma_xn is the population standard deviation and sigma_xn-1 is the sample standard deviation.

I can't seem to get my calculator into statistics mode. could you please explain it very clear. i must be mising something. i have a texas instrument calculator(Ti-30xA).thank you.


The TI-30Xa does not have a statistics mode. That statistics operations are available at all times, just like addition and subtraction. Just enter the data with Sigma-plus and then calculate the desired statistics---mean, standard deviation, and so forth.

Full details are in the "One-Variable Statistics" section of the guidebook (page 9 in my copy). If you need the guidebook, you can download one from

How do I convert from decimals to fraction with my TI-30X IIS calculator? I need the step by step process


The following examples will demonstrate how to convert decimals into fractions using the TI-30Xa and TI-30Xa Solar. Please be aware that TI-30Xa Solar School Edition calculators do not have this functionality.

Example: Convert .25 to 1/4
- Input .25, press [2nd][<--] (says F<>D above it).

** F<>D means fraction to decimal, decimal to fraction.

Example: Convert 1.38 to 1_19/50

- Input 1.38, press [2nd][<--].

Example: Convert 9.75 to 9_3/4

- Input 9.75, press [2nd]{<--].

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.

What kind of batteries and where can I find batteries for my TI-30A?


I hope you mean the TI-30XA, since TI never released a TI-30A.

The TI-30XA uses two A76 batteries, also known as 357. You should be able to find them at just about any department, electronics, or office-supply store.

Here's the full scoop on changing batteries:
