    Complex mathematical formula

    Hello friends,
    Since I'm mathematically challenged, I'm coming to you for wise assistance please.

    I'd like the simplest formula to calculate:

    The number that is 5% lower than the mean difference between 521 and 571

    *THE RESULT of the formula will be 518.7 (or 519). << (((571-521)/2)+521)*.95 >>

    I'm thinking there must be a simpler way to arrive at that number. This little formula will be used in a more massive IF/THEN/ELSE formula, so the shorter this is the better.

    Thanks in advance!

    Re: Complex mathematical formula

    Hi -

    You could just shorten it to =(571+521)/2*0.95

    Hope this helps.

    Re: Complex mathematical formula

    When you say "The number that is 5% lower than the mean difference between 521 and 571"
    do you really mean
    The number that is 5% lower than the mean OF 521 and 571

    or

    The number that is 5% lower than the difference between 521 and 571, i.e. 50

    ..or perhaps something else??

    Re: Complex mathematical formula

    Thanks. That works, but I wonder what is the purpose of using SUM since the answer is the same with or without it?

    As part of a longer formula it's helpful to use the full SUM() aspect for troubleshooting and correct calculation. (you may wish to add further calcs at a later date.

    Re: Complex mathematical formula

    You are correct, my question was not perfectly logical and should have been stated as your first interpretation.
    Fortunately, that's why I also provided what I knew the result of the formula should be.
    Thank you for taking the time to read, consider and respond to my request for assistance.
