Simplifying is the process of expressing a mathematical expression in the simplest
(and usually shortest) terms.
Note that only expressions can be simplified; equations have to be solved.

Slope
The rate at which the ordinate of a point on a line on a coordinate plane
changes with respect to the change in the abscissa.

Solve
Solving is the process of finding the solution set of an equation, inequality or
system of equations or inequalities.
This process usually involves explicitly expressing the solution value(s), and
checking whether the solutions that were found are valid.

Space holder

a space in an algebraic expression that the editor ‘reserves’ for

further input, so that the correct algebraic form is preserved. For example, when

you enter a /, the editor will display

to remind you that denominator has not

yet been entered. While you can skip the space holder and continue entering the
expression, you will not be able to solve the problem before replacing or deleting
the space holder.

Square
Square is equivalent to the second power.
For example, the expression :

could be read a squared.

Term
Term is any expression written as a product or quotient.

Trinomial
Trinomial is a polynomial consisting of three terms.

Variable
