    you arrange it in order of like terms (terms [separated by the plus or minus signs] that have the same variables attached)

    3a + 6 - 3a + 4

    = 3a - 3a + 6 + 4

    anything minus itself is zero

    = 3a - 3a + 6 + 4

    = 0 + 6 + 4

    = 6 + 4

    = 10

    Combine like terms:

    3a&-3a =0

    6&4=10

    0+10=10
