I'm French.

I would like to know:

  • How do you pronounce $\vec{A} \cdot \vec{B}$ : "A scalar B" or "A dot B" ?

  • How do you pronounce $\vec{A} \times \vec{B}$ : "A vectorial B", "A vector B", "A cross B" or "A times B" ?

In French we say "A scalaire B" and "A vectoriel B".

Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise. If this question can be reworded to fit the rules in the help center, please edit the question.


The first bullet would be read "$A$ dot $B$" or "The dot product of $A$ and $B$"

The second bullet would be read "$A$ cross $B$" or "The cross product of $A$ and $B$"

  • $\begingroup$ Thanks for your answer. But then how do we pronounce $\dot A = \frac{dA}{dt}$ ? Is it not pronounced "A dot" ? If yes, that would mean there is no difference in pronunciation between $\dot A$ and $\vec{A} \cdot \vec{B}$ ? $\endgroup$ – Quantum Force Oct 31 '14 at 16:30

    $\begingroup$ @QuantumForce: people will say "A dot", but the fact that one thing has two arguments and one thing has one inhibits confusion. I should also note that people will call ${\vec A} \cdot {\vec B}$ "the scalar product of A and B" and will call ${\vec A} \times {\vec B}$ "the vector product of A and B" $\endgroup$ – Jerry Schirmer Oct 31 '14 at 16:33

Rather, I pronounced it like $A$ bar dot $B$ bar. Or $A$ bar cross $B$ bar

    $\begingroup$ I downvoted because this answer is wrong in my opinion. Why bar? These are vectors. $\endgroup$ – Bernhard Oct 31 '14 at 19:11
