Question about Texas Instruments TI-30 XIIb Calculator

Use EE, which I believe is the shift of the key just above the 7. For negative exponents, use the (-) key just to the right of the decimal point, not the subtract key.

Exponents of 10 are entered by pressing [2nd][X^-1] (EE).

For powers of any base, enter the base, press the [^] (below PI) then enter exponent. Use the (-) white key if exponent is negative.

You probably want to calculate the numerical value of some mathematical expression with numbers raised to negative exponents.

Just enter the expression as you would with positive exponents Except that before entering the value of an exponent**press the change sign key, marked (-), or +/- or (+/-)**. Do not confuse the change sign with the usual minus sign, which is usually displayed bigger then the change sign. Make sure that the (-) is displayed before the value of the exponent. Use parentheses if necessary.

We had a similar problem: enter a number like 6.02 [x10n] 23

The 23 is shown as exponent, in small, raised type. How to get out of the exponent is not obvious, but my daughter finally guessed it. The right side of the direction control (>) exits the exponent.

Use the ^ key, located above and left of the 7 key. For example, to calculate 2 raised to the 120 power, press 2 ^ 1 2 0 =

1*10^(-3)

Because you're using -3 as an exponent, you need to put the whole thing in the parentheses.

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.

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.

Use the (-) key to the right of the decimal point. Use this key for entering any negative number.

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.
