The Distributive Property

Topics for Today:

Today we explored a the distributive property of multiplication over addition and subtraction.  Previously, we learned to perform operations according to a set of rules called The Order of Operations, and students refer to this concept at PEMDAS (pronounced pem-das).  When we have multiplication of a number by a quantity, we may also use the distributive property to solve.  When we progress to pre-algebra and solving equations, we will have to use this property to remove parentheses so that we may solve for our unknown.  Today, we used the property to rewrite multiplication problems to make them easier to solve.
