Consider the real numbers $a$ and $b$. I would like to express in math notation, that $c = 2$ if $a > 0$ and $b > 0$. Can I use the wedge symbol here like

$c = 2 \quad \text{ if }a>0 \wedge b>0$

or is this wrong usage of the wedge symbol? Is there a better way to express this?

    $\begingroup$ This is not a wrong usage of $\land$, but in that specific context, I'd prefer "and" $\endgroup$ Jul 22, 2020 at 15:57

    $\begingroup$ Overuse of logical symbols always make things harder to read (for no real reason). $\endgroup$

    $\begingroup$ I agree with @Randall. Better to write 'and'. $\endgroup$

    $\begingroup$ How you choose to write things like this depend largely on personal preference. I would just as easily chosen to write $(a,b)\in\Bbb R_+^2 \implies c = 2$, having skipped the "and" and instead written $a,b$ as a tuple. $\endgroup$

It depends on you. Anyway in my opinion "and" is more elegant choice in this case.
