**Algebra**- Writing mathematical phrases using letters to represent numbers.

Example:

*n*+6=14

*x*-6=3

**Variable**- a letter that represents a number in an equation or expression

Example:

*a*+11=20

**Constant**= the integer in an algebraic expression or equation

Example: 18+

*m*=8

**Expression**-pattern -many answers

Example: 3

*x*

**Equation**- only has one answer and an equal (=) sign

Example: 3

*x*=9

**Solving a One Step Equation**:

**1st**Isolate the variable

**2nd**Cancel the constant using zero pair

**3rd**Balance - do it to other side

**4th**Verify to check

Shane, I really like your use of colour, but why is there such huge spaces that aren't needed? Next time add a link to your post.
