Calculate cross product of 2 vectors

[tjsdndnjs]

Hello all.

First of all, I have two vectors a = [ 1 2 -3 ] and b = [1 2 0], and my task was to find the dot product a.b and cross product a x b

I somehow managed to do the dot product

Which gave me the answer. However, I am not sure how I could calculate the cross product of A and B...

I tried to do it similar to what I did with the calculating dot product but I have no clue how...

Could somebody help me on this?

Also, how can i print the name of the array and its contents to the worksheet?

Thank you!
