Operator: Vector Sum is a Vector Spell Piece added by Psi. It is a vector that is the sum of at least two vectors added together. It can be expressed as $\vec{v_{1}}+\vec{v_{2}}=\vec{v_{3}}$, where $\vec{v_{1}}$ and $\vec{v_{2}}$ are two vector addends and $\vec{v_{3}}$ is the summed vector. The operation can be imagined as two arrows, with the resultant vector being the hypotenuse of the angle created from putting a head of an arrow to the tail of the other. Having a vector pointing in the opposite direction is the same as vector subtraction.

A common use for this Operator is affecting a target block adjacent to a selected block by summing
Operator: Vector Axis Raycast and
Operator: Vector Raycast.

It is unlocked in the lesson "Vectors 101."
