The Distributive Property is an easy rule which you need for all your future math magic.
It helps you with simplifying equations and simplifying expressions, whenever you come across a sum (addition) or difference (subtraction) inside parantheses (brackets) that you have to multiply (multiplication) by a factor.
For example: 2·(3+4).
The Order of Operations, or PEMDAS (BEDMAS, BODMAS), tells you, to first start with the addition inside the parentheses (brackets), giving you 2·(7). Now you multiply by 2 and end up with 14.
But what happens, if instead of simple numbers or like terms you have to operate with unlike terms such as 2·(3-y)? Is there any chance to simplify this expression?
Here, the Distributive Property comes into play. It tells you how to solve any combination of terms looking like a·(b+c) or a·(b-c), where you can put in any number or monomial for a, b, and c. The Distributive Property tells you that if you have to multiply a sum by any factor, you can multiply each summand by this factor and add the resulting products. This works as well with subtraction inside the parentheses!
In this video you will discover the Distributive Property step by step with the help of a real-life example and learn in this lesson how to use it the right way. After watching the video you will never, ever have to be frightened again by scary-looking parentheses with sums or differences of unlike terms inside and with factors in front of them, such as x(a+b) or x(a-b).
With this method, you can simplify unlike terms such as 2·(3-y) into 6-2y. See? This doesn't look as difficult as before, does it?
Do you want to know how it works? Start the video right away and never get lost in expressions or equations with terns like a(b+c) again.
