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

SOURCE: cant get M2 off of my TI-30XA calculator

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...

SOURCE: Inputing scientific notation into my calculator

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

SOURCE: how do I reset the calculator after installing new

[OFF] ON/C] clears display, errors, all pending operations, constant calculations K, and STAT, but not M1, M2,and M3. Sets DEG angle units, floating-decimal format.
To clear memory M1 : Store 0 in 1
0 [STO] 1 clears M1
0[STO] 2 clears m2
0 [STO] 3 clears M2

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.

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...

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....

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