Question

Which expression is positive

Answer 1

I'm not sure if A B C D are answers, but I can say for sure that C is positive and A, B, and D are negative.

A:
$-7*13$
Since there is only one -1, the expression is negative;
$-7*13=91$

B:
$14*-2$
Here as well, there is only one -1, so the expression is negative;
$14*-2=-28$

C:
$\frac{-14}{-7}$
The -1 cancels out;
$\frac{14}{7} =2$

D:
$\frac{-42}{6}$
Here, you can't cancel the -1 out, so it remains negative;
$\frac{-42}{6} =8$

Sorry for the delay, hope this helps :)
