Do you mean four places behind the decimal point? Page 21 describes setting for fixed decimal point 0 thru 9 places to the right.

It calculator tells you Ram Cleared each time you turn it on, the most likely reason is that the backup battery is depleted. Its role is to keep the memory modules electrically refreshed when calculator is turned off. If the backup battery is dead, the memory is erased when you turn calculator OFF. Main batteries no longer supply power and the contents of the memory are cleared.

1. Check that main batteries are good and inserted in calculator.
2. Turn calculator OFF.
3. Replace the backup battery.
4. Turn calculator ON.
5. Press the [CLEAR] key to erase the "Ram Cleared" message.

### I ask my TI-83 Plus to calculate (-64)^(3/2) The TI-83 Plus says the answer is -512i, but I think the answer should be 512i. Is the calculator wrong or am I?

You're both right, in a way. (-64)^3 is -262144. The square root of that is +/- 512i. Take your choice as to the sign.

For what it's worth, the TI-84, TI-86, TI-89, and the HP 50g all go with the negative value.

### TI-83 countdown

Pressing 2nd then the up or down arrows is how you change the contrast on the TI-83. All you need to do is press the 2nd key then hold the down arrow to get your screen back. The countdown that you saw was just the value the calculator assigns to the contrast. It goes from 0-10.

Hope that helps!

### Find the antilog on the TI-83 Plus for finding pH in chemistry problems

I reccently had the same problem, but I have a Ti-84 Plus,and I am disgusted by how poorly this matter is covered by Texas Intruments. Esp. since the solution is rather simple.

The antilog key is [2nd] [log] or the 10^x. On your screen it should apear as 10^( and then you just input the value that you want to find the antilog of.

When used to solve pH problems remember to input the pH value as a negative number, since pH= -log[H+] then [H+]= antilog(-pH).

Hope that helped))))) ^^
