Usage notes
In mathematical terms, the scalar triple product of three vectors $$ \mathbf{a}\ $$, $$ \mathbf{b}\ $$ and $$ \mathbf{c}\ $$ is $$ \mathbf{a}\cdot(\mathbf{b}\times \mathbf{c}) $$, or the scalar product (dot product) of $$ \mathbf{a}\ $$ with the vector product (cross product) $$ \mathbf{b}\times \mathbf{c} $$. It is a scalar quantity.
