  16. 8*19 = 8 * (20 - 1) = 8*20 - 8*1
    = 160 - 8
    = 152
    or if you want to get fancy
    8 * 19 = (10-2)(20-1) = 200 - 10 - 40 + 2
    = 200 - 50 + 2
    = 152
    :)

  18. 2(9+3) = 18 + 6 = 24
    or
    2(9+3) = 2(10 + 2) = 20 + 4 = 24
    or
    2(12) = 24
    whatever :)

  20. 9*81
    oh fun
    (10-1)(80+1) = 800 +10 -80 - 1

  23. 1. 8*19 = 8*(11+8).

    2. 2(9+3) = 2 * 12.

    Note: The quantity in parenthesis is replaced by its' equal.

  36. Using the distributive property, an expression equivalent to 48 + 30 is

    1. 👍
    2. 👎
  37. 1. (8 x 20) - (8 x 1)
    2. (2 x 9) + (2 x 3)
    3. (7 x 50) - (7 x 2) = 350 - 14 = 336
    4.(9 x 80) + (9 x 1) = 729

    Now idk if these are exactly in order, but I got 100%.
