Yes - thank, I understand that.

The confusion was that the person in the video I watched GRAPHED that 9 + 7.5 result as a VECTOR!!

Yes - that's what I thought was right - a scalar of 16.5

So, is the operation I wrote out - which I saw someone else do - not a valid operation at all?
I didn't think it was but it left me confused.

Hello,
Can someone help me with basic vector multiplication please.
I understand (I think!) dot product (scalar result) and cross product (vector result), but I was watching a video where someone did this

writing this in the format of x axis, y axis...

vector a:  3, 1.5
vector b:  3, 5

and multiplied them as:

3 x 3 = 9
1.5 x 5 = 7.5

claiming  the result of multiplying the vectors was a vector: 9, 7.5

Is that right?
