    Hi...


    can anyone help me how to imput an equation onto my calculator.

    the calculation is a simple Nernst equation working out resting membrane potentials, and even though I do understand the concept I just don't really know how to use my calcuator properly to get the correct answer!

    58mv/1 log (20)/(400) = -75

    I have a calculator that looks something like this btw http://www.casio.com/products/Calculators_&_Dictionaries/Scientific_&_Financial/FX-300ES/

    cheers

    on a similar Casio fx-83ES

    I entered:

    5 8 ÷ 1 log ( 2 0 ) ÷ ( 4 0 0 ) ) =

    and it returned:

    -75.45973975
