You don't. The 30X IIs runs on both solar power and a 2025 lithium battery. If you need to replace the 2025 battery, see this.

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]{<--].

- Input .25, press [2nd][<--] (says F<>D above it).

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

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

Input n, press 2nd [nCr], input r, press =.

For example, to calculate the number of thirteen-card bridge hands that can be dealt from a deck of 52 cards:

5 2 2nd [nCr] 1 3 =

If you have an older version on the TI30x Solar (not TI30Xa or newer) then you must use a different key sequence for nPr/nCr.

52 [2nd][x/y] 5 [2nd][nCr] gives 2598960 (the x/y button is above the Pi symbol on my version).

8 [2nd][x/y] 3 [2nd][nPr] gives 336

This took me forever to find out, so hopefully it will help someone!

Press 2ND [CSR] to clear the stat data.

For each data point, enter the number followed by SIGMA+

If you have grouped data, enter the number followed by 2ND [FRQ] followed by the frequency then SIGMA+

Press 2ND [sigma x n] for the population standard deviation or 2ND [sigma x n-1] for the sample standard deviation.
