In math, things that can change are called variables. The things that do not change are called constants.

vector space

A vector is a quantity having magnitude and direction, represented by a directed arrow indicating its orientation in space. Vector space is the three dimensional area where vectors can be plotted

velocity

The rate of change of position over time is velocity, calculated by dividing distance by time

Venn Diagram

A diagram where sets are represented as simple geometric figures, with overlapping and similarity of sets represented by intersections and unions of the figures

vertical angles

The two nonadjacent angles formed when two straight lines intersect

volume

A measure of the number of cubic units needed to fill the space inside an object
