What about my answer do you not understand?
What does your textbook say about subspaces of vector spaces?
All of it
My lecture notes show that for it to be a subspace it has to satisfy three axioms.
I know that 0 belongs to V, but how would i apply that to skew symmetric matrices?

Is the sum of two of skew symmetric matrices a skew symmetric matrix?
If you multiply a skew symmetric matrix by a real number do you get a symmetric matrix?
Yes. Now answer the two question.

Yes i do
How can I show V is not an empty set....1st axiom
EDIT: Lol its pretty obvious now. I just have to write down any skew symmetric matric i guess. Thanks. You made it sound much easier.
