of a numerical expression
The number that is the result of evaluating a numerical expression.
Ex: the value of 2+3X4
is 14. Remember,
the order of operations says that multiplication must be done
first when evaluating this.
of an algebraic expression The
number that is the result of evaluating an algebraic expression.
Ex: the value of 3y
+8 = 11 is 1.
of a variable
A number that is substituted for a variable.
A symbol that can stand for any one of a set of numbers or other objects.
A quantity that has both magnitude and direction.

of the sides of an angle.
The angle included by equal sides of an isosceles triangle.
Here the vertex angle is at the top.
Any of the vertices of the faces of the polyhedron.
nonstraight and nonzero angles formed by two intersecting lines, but which
are not a linear pair. Vertical angles will always be congruent.
component of a vector
The second component in the ordered pair description of a vector, indicating
its magnitude along the y-axis of the coordinate plane.
||Ex: Here we see
a vector with an ordered pair description of (7,3). Three is the vertical
component of this vector.
A line with an equation x = h on the coordinate plane.
Ex: The line x
= -2 has every x value locked at -2 for every value
of y, and it looks like this:
of the space inside a three-dimensional, or solid figure. The number of
unit cubes or parts of unit cubes that can be fit into a solid. Also called
