Subtraction, Addition, Multiplication, and Division Properties

These properties are all pretty much the same things so I've decided to put them all in one post.

The Addition Property is when you add something to both sides of an equation such as when you are solving an algebraic equation:

x-3 = 9
  +3    +3  <---
x = 12

Did you catch that?


The Subtraction Property is when you subtract something to both sides of an equation such as when you are solving an algebraic equation:

x+5 = 9

    -5   -5 <---

x = 4

See? Pretty simple.

The Multiplication Property, as you may be able to guess by now, is when you multiply something to both sides of an equation such as when you are solving an algebraic equation:

x/4 = 2
 *4    *4 <---
x = 8

Piece of cake.


The Division Property is when you divide something to both sides of an equation such as when you are solving an algebraic equation:

4x = 8
 /4    /4
x = 2

Remember, if you have any questions, comment.
