Use the EE key, just as for positive exponents. Just make sure you use the +- key (next to the decimal point key) to enter negative values, not the - key which is for subtraction.

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.

TI-30x...I am trying to figure out how I use this calculator


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.

1.19x10-4=?


You can download the guidebook for this calculator from TI here.

From page 16:
To enter a number in scientific notation:
1) Enter up to 10 digits for the base (mantissa). If negative, press the +/- key. (The key has two curvy arrows between the + and - but I can't do that on my keyboard.)
2) Press the EE key.
3) Enter a 1 or 2-digit exponent. If negative, press +/- either before or after entering exponent.

They give the example 1.2345 +/- EE +/- 65 which would display -1.2345 -65.
