The multiplier point logic is confusing and wrong

[3esmit]

I am refactoring this logic to be like read like a poem.
Needed for #48

The code is written like math formulas and there is a lot of code duplication.

• Remove all ` (a == b) ? "case true" : "case false";´ and turn them into a if/else case.
• Encapsulate the math operations and reuse the same formula whenever is needed
• Optimize the use of if/elses

Done!
