- Every instruction has a label specified by number followed by a colon e.g. "4:"
- There are 3 types of instruction:

  1) Value x         - Returns the value x
  2) Add <labels>    - Evaluates the instruction at each label in <labels> and adds the result together
  3) Mult <labels>   - Evaluates the instruction at each label in <labels> and multiplies the results together

  <labels> is a list of one or more numbers that refer to the label of other instructions in the input.

- The overall result for a set of instruction is the result of evaluating the first instruction.

0: Add 4 4 1
1: Mult 6 2
2: Value -3
3: Add 6 1 2
4: Value 5
6: Value 2

        Add 4 4 1
  ->    Add (5) (5) (Mult 6 2)
  ->    Add (5) (5) (Mult (2) (-3))
  ->    Add (5) (5) (-6)
  ->    Add (10) (-6)
  ->    (4)
