This lesson covers the distributive property. Students learn the distributive property, which states that a(b + c) = ab + ac. In other words, the number or variable that is outside the set of parentheses "distributes" through the parentheses, multiplying by each of the numbers inside. Note that a negative sign outside a set of parentheses can be thought of as a negative 1, so a negative 1 distributes through the parentheses.
