Silly question about Cross-Product

[Saladsamurai]

I just forget the rule here.

I am finding angular momentum by using r x mv

If I am using the determinant to evaluate r cross v, where does the mass come in? Do I just mulyiply the result of r cross v by m?

Or do I distribute m to my vector v and then use those values inside the determinant?

It doesn't matter. m is just a number, so
r x (m v) = (m r) x v = m (r x v)
