Algebra

variable- a letter that represents a number in an equation or expression.
constant- the constant is the integer in algebra. n+5 -- +5 is the constant
expression- a pattern that has many possible answers.
equation- has only one possible answer.

One-step equations:

1. Isolate the Variable
2. Cancel the Constant using a Zero Pair
3. Balance (do to both sides)
   
4. Verify to check
