The cross operator (2x3=6) or the dot operator (2⋅3=6)?
In school, what symbol did you use to denote multiplication?
EducationWell, in Spain is quite weird, In primary education (6-12) it's used 'x' but from secondary school (13-18) onwards, it's used the dot.
Why?? I've asked many people related to education and math and no one can give me an answer.
This. The explanation I got: in calculus in primary you only learn the basic arithmetic stuff. (3x9 = ??) In secondary school you also get stuff like 2x+6=56. What is x.
To avoid confusion between the operator and the other one, you start using the dot for multiplying.
In the Netherlands did you write the unknown "x" as two crossed lines? In the UK we always had to write it like ")(" so it was obviously different than the multiplication "x"
I haven’t learned any rules concerning how to write variables. But because we don’t use the x for multiplication, it doesn’t really matter how you write the variable x.
