Use the inverse log key sequences "2nd LN" or "2nd LOG" depending on whether you are using natural logs or logs to base 10

Remove the six screws on the back cover. After the batteries are installed you need to reset the board. There is a little reset area that needs to be shorted to get the calculator back to normal. Look closely at the circuit board- You'll see a little circle next to the word reset. Its near the middle of the board. Wet your finger- press it on the circle. It should short. Blow it dry with your breath. It should work...

Hello,

1. To convert a number to scientific equation, use [2nd][Sci]
Exemples 12345 [=] screen shows 12345 Then [2nd][Sci] coverts it to 1.2345 ^04 to the power 4.
2. To enter directly a number in scientific notation (e.g. -1.2345 X10^(-65) a very small number) you use the [EE] key 1.2345[+ /-][EE][+/-]65 shows as -1.2345 -65
1.6X10^(-19) 1.6[EE][+/-]19 shows as 1.6 -19

Hope it helps

To clear memory M1 : Store 0 in 1
0 [STO] 1 clears M1
0[STO] 2 clears m2
0 [STO] 3 clears M2

SOURCE: Can you calculate nCr ?

Yes. Use the 2nd [nCr] function.

52 2nd [nCr] 5 = will calculate the number of 5-card poker hands that can be dealt from a deck of 52 cards.

### Okay so i am using a TI-30XA What is the button on this calculator for (Prb) ??

There is no probability key on the 30Xa as there is on the 30XIIS. The shifted functions of the 8 and 9 keys will calculate the number of combinations and permutations, respectively. The shifted function of the 3 key will calculate the factorial. There is no random number generator.

### How to get the square root using a ti-30xa calculator?

Come on now....there are dedicated "square" and "square root" keys on the TI-30XA....

Enter your number e.g. 4, then press the "root x" key to get 2...

Press "x squared" key to get the square of 2 = 4

There's the even more useful "y to the power x" key and it's inverse "xth root of y" key.

E.g. Enter 2, then press the "y to the power x" key, then 5, then =, answer is 32 (2 x 2 x 2 x 2 x 2). Starting with 32, pres 2nd then the "y to the power x" key, then 5, then =, answer is 2, the 5th root of 32....

### The e to the x button

If you mean (e to the power x) minus 4, where x = -1, the key sequence would be:

1
+/- (above 3 key)
2nd
LN
-
4
=

Result is -3.63212.....

If you mean e to the power (x-4) where x = -1 again, it's:

10.0067379....
+/- (above 3 key)
-
4
=
2nd
LN

### Ti-30xa

Display has gone....you will have to buy a new calculator, fortunately the TI-30XA is only \$10-\$15!!
