Algebra:
Algebra is a branch of mathematics that substitutes letters for numbers.
Algebraic equations:
A scale, what is done on one side of the scale with a number is also done to the other side of the scale.
Variables:
Variables are symbols that are usually defined to denote any member of a set of objects.
Functions:
Functions are relations, such that each element of a set is associated with a unique element of another set.
VANG:
VANG stands for
Verbal
Analytical/Algebraic
