I really can't understand uncertainty

    I really can't understand "uncertainty"

    Hi guys,
    I really can't understand "uncertainty"...
    How it works, and Why it works
    I don't understand..
    Like why:
    4+/-0.5 x 5.2+/- 0.2
    =4x5.2 +/- 0.5 x 0.2?

    Would anyone be kind enough to elaborate a bit for me?
    Thanks for reading

    Re: Uncertainty

    Why moved it here?
    It is not homework, not coursework either That was just an example....
    If any naive post will be moved, then who will ask questions here?
