What you call 'basic skills' apparently includes to call negative 
numbers 'positive'.

I cannot follow you here, because to me this sounds disgusting.

In physics velocity is always a vector and has always a direction.

If you like to address the amount, you could do so and omit the sign and 
direction by writing |v|.

If you don't, v is a vector.
