How do you know which approach to take for a given problem? How do you compare different approaches, and how do you know your answer is correct? There are many proofs hidden under the "solving" or "computational" part, unless, you were taught by other people and you don't bother to challenge.
Complicated skills contain many small steps of proofs.
