**1**. A type of vector multiplication. If **i**, **j**, and **k** are mutually orthogonal unit vectors so that two vectors **A** and **B** may be expressed in terms of components in these directions:

and

then the cross product **A**×**B** is orthogonal to both **A** and **B**:

Also called **outer product**.
