Distributive Law

🎬 Video Tutorial

  • (0:01) The Distributive Law: States that multiplying a number by a sum is the same as multiplying it by each part separately, then adding the results. This also works for subtraction.
  • (0:52) Expanding and Factorising: The distributive law helps in both expanding expressions (e.g., 15 × (100 + 2) = (15 × 100) + (15 × 2) and factorising, such as 50 × 24 − 50 × 14 = 50 × (24 − 14).
  • (2:23) Distributive Law and Division: The distributive law generally doesn’t apply to division, so it’s best used for multiplication, as dividing terms within brackets doesn’t simplify effectively.
