    Help please!

    Two associative functions on the the unit square:
    [0,1]^2 -->[0,1]
    x,y --> T(x,y) and S(x,y)
    What is the ordinal sum of these two functions on [0,1]^2 ? I know it is not T(x,y)+S(x,y)
    Does ordinal some have something to do with ordinal numbers?

    for particularly this problem it is the sum of all the ordered pairs who are transitive. i.e. follow the transitive properity.
