  • Distributive Law -1-
    Each value in the brackets is multiplied by the factor in front of the brackets.

    3 × 17 + 3 × 13 = 3 × ((17 + 13))
    51 + 39 = 3 × 30
    90 = 90

    General:
    a × b + a × c = a × ((b + c))
       a,b,c ∈ ℕ0
  • Distributive Law -2-
    Each value in the brackets is multiplied by the factor in front of the brackets.

    8 × 27 - 8 × 17 = 8 × ((27 - 17))
    216 - 136 = 8 × 10
    80 = 80

    General:
    a × b - a × c = a × ((b - c))
       a,b,c ∈ ℕ0
