Essentially Maths is just a way or tool to help us to solve the problem.
Let's say we going to sum from 1 to 100 (Gauss anyone? 😉), we got 2 options:
☑ Write a loop begins at 1 and accumulate the sum until 100
☑ Compute with formula: (100 × 101) ÷ 2
We still get the same output for both options but we can see that the latter is more efficient.
