9/23 – Distributive Property

The distributive property says there are always two ways of counting something: ALL AT ONCE or PIECE BY PIECE.

For example, if you have 3(2x + 6), then it’s also truthful to say that you’ve got three 2x’s and three 6’s.  In other words, 3(2x + 6) = 3(2x) + 3(6).  The purpose of today’s lesson was to apply the distributive property to variables.  Note that this calls upon our old ability to multiply monomials like (2xy)(3x).
