Mathematics branch of mathematics that uses basic operations to solve expressions

Linear equations:
A linear equation is an equation involving only the sum or product of constants and the first power of a variable.
y=f(x)=mx+b where m is the slope and b is the y intercept is the general form of an equation in slope intercept form.
The formula of a slope= where and are two points in ordered pair form.
The general form of point slope form is:
 where m is the slope, and is the two points in ordered pair form.  

Polynomial equations:
The quadratic formula equals:
 where a, b and c are constants of a quadratic equation is of the form
.

Factoring:
Factoring is a process of dividing out a factor from a mathematical expression.
Common factors technique is of the form ax+bx=x(a+b).
Difference of squares: .
Difference of cubes: .
Rationalizing is the process of removing an irrational expression from the numerator of a fraction.

Order and Inequalities:

Number line: An axis or ray usually horizontal on which real numbers are represented and ordered from left to right.

Absolute value: For a real number a, it is a if a is greater than or equal to zero or –a if a is less than zero. It is denoted.

Conic sections:
The general equation of a circle:
. Where r is the radius of the circle and  is the center of the circle.
The general equation of an ellipse:
.
