It deals with the concept of variables, Equations and Polynomials.
Inequality: It is used for comparing two expressions. <, ≤, >, ≥
Like terms: The terms which have same variable and rose to the same power.
Polynomial: It contains a group of terms with variables and whole number exponents.
Solving for unknown variable
Example: x +5 = 3 (solve for x)
x = -2
Arithmetic operations on variables
Example: 2x + y = 4x -5 (write y in terms of x)
y = 2x - 5
Order of operations: PEMDAS rule
Slope intercepts form
y = mx + b
Factoring of polynomial equations
