Some high-end calculators have a Computer Algebra System built-in. These systems can do symbolic algebra, that is, with symbols instead of numbers, for example factoring a^2-b^2 to produce (a+b)(a-b).

The TI-30x isn't one of them.

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.

You can use FIX notation display but specify the number of digits you retain. Press [2nd][FIX] and select the number of digits after the decimal mark (from 0 to 9). However if you do you will constantly have many unnecessary 0.

You can set the display to FLOAT.

To do so, press [2nd][SCI/ENG]. From the three choices you have select FLOAT.

The TI-30Xa replaced the TI-30X within a year. The only enhancement was the added Constant key.

The TI-30XII, introduced about five years later, is a significantly different calculator, incorporating, among other things, a two-line display.

Hello,

Entering the keys and number as you write it can be done with enough parenthees to make sure calculator does what we intend it to.

But I would rather use the commutativity propertie of multiplications to same me some extra ().

Step 1

4 [(+/- change sign)][2nd][10 to the x] [ X ]6.1923 [=]

Step2

[x^2][=]

I first calculate the product 6.1928 x 10^-4 then take the square of the result. Because you can never be sure that the calculator takes 6.1923 to power 2 then multiply or multiply 6.1928 x 10^-4 and raise to power 2.

You can force the calculator with an opening parenthesis and a closing one but if you omit the ) and get an error, it may be hard to detect.

Hope it helps.

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.
