How do i calculate the pH of a solution on the casio fx-260 solar calculator?

Yay, thank you so much!

Try them by yourself or read the manual. You should be able to figure out most of them.

The FX-901 calculator seems to be the equivalent of the FX 260 Solar sold in North America. It does fraction calculations, permutation, statistics but lack the Equation Solver.
You cannot use it to solve equations.
Casio Scientific calculators that can handle equation solving are the FX-115 and FX-991.
Simplify your first equation by dividing all its terms by 3, then use elimination to carry out the solution by hand.

This can be done by setting the calculator to the right MODE. Press MODE 9 to turn on scientific notation. For example, compute 1 / 200 = and you will see 5 with a -03 exponent in the upper right. Press MODE 9 again and it will be displayed .005

To enter numbers in scientific notation use the EXP at the bottom. To enter .005, press 5 then EXP then +/- then 3. You will see it displayed. Then you can perform calculations with this entered number.

Hello,
Yes it does. All scientific calculators do logs, power, roots, exponential, trigonometric functions. Most do also hyperbolic and inverse hyperbolic functions.
Hope it helps.
