1) Complex  Numbers
(a) Irrational Numbers

Example: $\sqrt 3$, $\frac{1}{\sqrt 2}$
Example: $2 + \sqrt 5$
(c) Imaginary Numbers
Example: $i$ = $\sqrt -1$, $i^2$ = $-1$.

(d) Complex Numbers in the form
$a + \sqrt b$ OR $a + bi$
(e) Adding / Subtracting Complex Numbers
(f) Multiplying / Dividing Complex Numbers
Example: $(2 - 3 \sqrt 5)\ \times\ \sqrt 3$
(g) Conjugates of Complex Numbers
Example: Conjugate of $2 + 5i$ is $2 - 5i$
(h) Rationalising Fractions with Complex Numbers in Denominator
(i) Transcendental Numbers
Example: e-Euler number, $\pi$

2) Equations and Inequalities

(a) System of Linear Equations
Example: Solve $3x - y$ = $6$ and $x + y$ = $4$
(b) System of Non Linear Equations
Example: Solve $x - y$ = $4$ and $x^2 - 2y$ = $7$
(c) Rational Equations

(f) System of Linear Inequalities

Numerical and Word Problems

Example: Solve for Region of Inequality for $x \geq 4$  and $y < 3x - 5$

Finding the factors of $x^2 - 6x - 12$
(c) Completing the Square
Use the identity $(a+b)^2$ = $a^2 + 2ab + b^2$
(d) Sum and Product of Roots
(f) Word Problems
4) Exponents and Logarithm

5) Exponential Growth and Decay

(a) $A$ = $P(1 + r)t,\ A$ = $P(1 - r)t$
(b) Solving Exponential Equations
(d) Word Problems on Exponential Functions
Compound Interest, Population Growth, Half Life Period
6) Rational Expressions and Equations

Rational expressions are similar to fractions that have variable expressions in numerator and denominator.

(a) Simplifying Rational Expressions using Factorization
(b) Addition/Subtraction, Multiplication/Division of Rational Expressions
(c) Restrictions/Discontinuity of Rational Functions
Example: $\frac{x + 3}{x - 3}$
Cannot have the value $x$ = $3$ as it will make the denominator zero and hence the expression undefined.
(d) Solving Rational Equations
(e) Solving Rational Inequality

(a) Solving Square Root Equations
(b) Solving Cube Root Equations
