    13 (mod 3)  is the remainder of division of the number 13 by 3.

    So,  13 (mod 3) is 1   (13 = 4*3 + 1, therefore, 13 (mod 3) = 1 (mod 3) ).



    32 (mod 3) is the remainder of division of the number 32 by 3.

    So,  32 (mod 3) is 2   (32 = 10*3 + 2, therefore, 32 (mod 3) = 2 (mod 3) ).



    Therefore,  13 - 32 (mod 3)  = 1 - 2 (mod 3) = -1 (mod 3) = 2 (mod 3).  



     ANSWER.  13 - 32 (mod 3) = 2 (mod 3).
