An Operation is the Type of Work a person does to Calculate a Problem.
A Calculation is the Process of Deductive Reasoning, Adjustments, Balances, Summarizations, Integrations, and Simplifications done to Identity and/or Determine a Solution.
An Equation is a Logical Proof — usually composed in Symbols and Mathematical Shorthand — so you can apply the Operations in the correct Logical Sequence to determine the Solution.
A Word Problem is a Real Life Situation needing to be composed into a Logical Proof then simplified into an Equation before it has been built into a Logical Proof by the Student.
