    When I see **** like that I am very thankful for Matlab or http://www.wolframalpha.com

    I hate calculus and linear algebra with a passion. I liked discrete math because there were a lot of tie-ins to crypto.

    It's weird to have different emotions for different types of math...I blame college.

    I honestly wish I spent more time learning Matlab in school. I did get a bunch of time playing with simulink doing filter design.
    Could you imagine doing notch Filter design work by hand? I did one that was a 47th order polynomial.

    Don't you think that's a little ahead of the curve for someone who hasn't had to think about PEMDAS in over half a decade? I'd be up all night reasearching and refreshing to puzle that out.

    My experience had more to do with acoustic engineering and the problems were very simple.

    I.E., Helmoltz Wave Traps:

    Speed of sound / frequency = Wavelength Wavelength /4 = trap length (The equation can be reversed to determine frequency from wavelength as well.)

    The trap reflects a standing wave 180 dgress out of phase with itself canceling the offending frquency and it's octaves. Easy peasy. Not hypothetical. That is what I was talking about.(Where on earth do you get a two dimentional truss?)

    But go ahead and call me stupid for not being fresh on math which I haven't needed since 2004.

    The reason the answer is 1 is because there are two parenthesis operations in the original, not one.

    6/2(2+1) = 6 / 2(3) = 1

    is not

    6/2*(2+1) = 9

    Interesting point, so why did the CAS in the Ti-89 and Wolfalpha miss this?
    Because of the distributive properties
    6/2(2+1)==6/(4+2)
    6/6

    Discrete Mathematics was the most important class I ever took in my life. It should be required for everyone.

    Holy **** I do remember some algebra.
    1 was to easy, so I gave up.
