Operator: Vector Subtract

Operator: Vector Subtract is a Vector Spell Piece added by Psi. It is a vector that is the Subtract of at least two vectors added together. It can be expressed as $$\vec{v_{1}}-\vec{v_{2}}=\vec{v_{3}}$$, where $$\vec{v_{1}}$$ is the minuend, $$\vec{v_{2}}$$ is the subtrahend, and $$\vec{v_{3}}$$ is the difference. The operation can be imagined as two arrows, with the resultant vector being the hypotenuse of the angle created from putting the two original vectors tail-to-tail, with the resulting vector head pointing towards $$\vec{v_{1}}$$. Having a vector pointing in the opposite direction is the same as vector addition. It is unlocked in the lesson "Vectors 101."
