    RE:

    I can't read any of your other questions, because of the notation. It is quite messy.

    your formatting method isn't working. whenever you type a lot of spaces, the forum truncates them, so it defeats the purpose. please retype your questions using parenthesis and "/" for division signs

    r+9/4 + r-3/2



    2r+6/6

    Hello,

    I assume that you mean:
    Code:
    r + 9   r - 3   r + 9   2(r - 3)    r+9 + 2r - 6    3r + 3
    ----- + ----- = ----- + -------- = -------------- = ------
       4      2       4       4             4             4
