* Fixed typos and changed OO to OOP
Some typos, mainly to ease the reading for Portuguese people.
Changed every OO to OOP because it was confusing, and calling it OOP like every other language calls it, makes it even easier for begginers to search online more information about the subject.
* Fixed the sentence that should be in PT-BR
Changed "porquê" to "por que" because is correct in PT-BR
Intermediate code solution doesn't pass tests when the greater number is even because it's the starting acc without passing the reducer function that avoids even number.
Proposed solution: reverse the array before reduce.
Fixed copy/pasting(?) typos, also changed the 'because' in each example to explain the why instead of just showing it's true for a single number, not mentioning any others. (Proof by example is very, very, VERY bad to encourage.)
Presented formula, derived it and gave examples, one simple and one more involved to show how it's not always 'easy' or 'obvious' how this rule can be applied to help, a rule of thumb in how to use it and a brief list of generalizations.
