i finally fixed my calculator~
1. if you have a ti 84 plus silver, plus, or just ti 84, find a friend who has either a ti 84 plus silver, plus, or just ti 84. (as long as the number is the same)
2. link the two calculators together
3. using your friends calculator, press the [2nd] and the one next to alpha [x,t,o,n]
4. go all the way down to [send os]
5. send it to the other calculator and your problem should be fixed

The problem is simple. You're trying to get an [H+] concentration which is obviously going to have a value of some number times ten raised to a negative power. Therefore, you have to insert the negative value of the pH into the 10^(x). When you insert said negative number you will come out with the right answer.
The pH of a sample of human blood was calculated to be 7.41. What is the [H+] concentration of the blood?
10^(-7.41) = [H+]
[H+] = 3.9 E-8
(the answer should only have two sig. figs because the pH has two digits after the decimal.

I'm not specifically familiar with the TI83 or TI84 but I've used a lot of TI calculators in my time, so I'll give it a try. If your trying to find the antilog of a number in base 10 enter the number and hit the (10 to the X) button. If you're trying to find the antilog of a number in in base e (natural log), enter the number and hit the (e to the X) button.
