Cross Product :

The vector product of two nonzero vectors a b and r r is denoted by a br r
and defined as

where θ is the angle between a b and r r, 0 ≤θ≤π and nˆ is
a unit vector perpendicular to both a b and r.

To find cross products of two or three vectors we have many online cross product calculator  s where you can get results instantly.

when the positive x-axis is rotated counterclockwise into the positive y-axis, a right handed screw would advance in the direction of the positive z-axis.

In a right handed coordinate system, the dumb of the right hand points in the direction of the positive z-axis when the finger is curled in the direction away from the positive x-axis toward the positive y-axis.
