Homework Help: Order of calculations in a matrix problem.

  1. Jan 22, 2013 #1
    1. The problem statement, all variables and given/known data
    (A+2D)T


    2. Relevant equations



    3. The attempt at a solution

    I believe this would become AT+2DT. My only question then is, do I multiply the transpose of matrix D by 2, or multiply matrix D by two and then take the transpose? Thank you.

    There's really no difference, is there?

    Excuse me while I hang my head in shame.
