- variable: is a letter that represents an unknown number in algebra (ex: a, q, t, k)
- constant: is the integer in an expression or equation (ex: x +6)
- expression: is a pattern and has many different answers (ex: 2x)
- equation: has an equals sign and has only one possible answer (ex: 2x=6)

How to solve One Step Algebra Equations:

1) Isolate the variable

2) Cancel using the opposite (cancel the constant using a zero pair)

3) Balance both sides (do the same on both sides of the equal sign)

4) Verify to solve equality

How to solve Two Step Algebra Equations:

1) Isolate the variable

2) Cancel the constant

3) Balance both sides of the equals sign

4) Simplify the variable

5) Balance both sides of the equals sign again

6) Verify to check
