    A = (6 – 2/3 + 1/2) – (5 + 5/3 – 3/2) – (3 – 7/3 + 5/2)
    A = 6 – 2/3 + 1/2 – 5 – 5/3 + 3/2 – 3 + 7/3 – 5/2
    A =( 6- 5 – 3) -( 2/3+ 5/3 – 7/3) +( 1/2 + 3/2 – 5/2)
    A =-2 – 1/2
    A=-5/2

    A = (6 – 2/3 + 1/2) – (5 + 5/3 – 3/2) – (3 – 7/3 + 5/2)
        = 6 – 2/3 + 1/2 – 5 – 5/3 + 3/2 – 3 + 7/3 – 5/2
        = ( 6 – 5 – 3 ) + ( -2/3 – 5/3 + 7/3 ) + ( 1/2 + 3/2 – 5/2 )
        = ( -2 ) + 0 + -1/2
        = ( -2 ) + -1/2
        = -2/1 + -1/2
        = -4/2 + -1/2
        = -5/2
