The Distributive Property

The Distributive Property is useful because of the unknown nature of Algebra. Back in the good old days (elementary school), this type of problem would be presented:

Simplify 5(8-2).

Order of Operations dictates the sequence of completing mathematical operations.

1. Parenthesis
2. Exponents
3. Multiplication or Division

To simplify 5(8-2), use the following steps:

5(8-2)

1. 5(6)
2. 5*6 = 30

Distributive Property Example

What if the exercise looked like this?

Simplify 14(3 +x).

Nothing can be done inside of the parenthesis because 3 and x can't be combined. Don’t dismay, the distributive property is here to save the day!

Illustration of the Distributive Property

a(b + c) = ab + ac

In other words,

14(3 +x)

1. 14*3 +14*x
2. 42 + 14x

Be careful, 42 + 14x is not 56x.
