If an algorithm does more computations compared to another, is it faster? Or is it slower as it has to do more computations? Is there a difference between computation and operation?

In Q1 : L does 500 operations and is thus deemed slower.

In Q2 : L does 20000 computations while Q does 4200 but L is called faster.

In Q3 : Q does more computations (~10^5) but is called slower.

I believe there's an** error**. Am I missing something?
