I love all that tastes like mathematics, particularly number theory and history of mathematics.

@amWhy, sorry, I started writing before, but when I published the answer I had not yet seen another answer.

 comment How to solve this? (adding polynomial fractions)
@Cypras, because i need have a denominator in the two fractions such that both are equal, this, because you know that if i have two fractions $\frac{A}{B}$ and $\frac{C}{B}$ then, the sum of the 2 fractions is $\frac{A+C}{B}$ and so it is easier to add, (it is equivalent to searching the common denominator, which is the same thing amWhy said)

 comment What symbol should I invoke in order to present the angle between two vectors?
I think your symbol is used when you have a triangle ABC to say that ∠ABC is the angle formed by the intersection of sides A and C, but I do not think you can use if you talk about vectors
