    Simplification too simple?

    Alright, ive got 10 problems specifically based on Simplification. at first they were easy, simple stuff like (-5)(-w)(w)(w), but after a while it became this:

    8(4-q)

    (6+y)(12)

    (35-10q)(-2/5)

    -9(y+11)

    5(3-z)-z

    arent they already as simple as it gets? we had a sub today, so i couldnt ask, and its due tomorrow

    to expand brackets, you take what is outside the brackets and multiply everything that is inside.

    example: -2(x + 3) - 4

    expand the brackets first. we take -2 and multiply everything in the brackets, so we get:

    -2x - 6 - 4

    now we simplify

    -2x - 10

    and we're done.

    so you would write:

    -2(x + 3) - 4 = -2x - 6 - 4
    ..................= -2x - 10

    now do all your problems like that

    if you raise a negative number to an even power, the result is positive. if you raise a negative number to an odd power, the result is negative.
