Irrational numbers – A real number that is not rational. The decimal form neither terminates nor repeats.
Cartesian product – 迪卡兒乘積
Quadrilaterals – can be divided into several subcategories base on characteristics such as angles, parallelism, and side length.
Absolute Value and Inequalities
|x-12| = 3 – x -12 = 3 or x – 12 = -3
x = 15 or 9
Transversal – A line that intersects at least two other lines
|n| – absolute value; when solving you have to find both positive and negative solutions
Zero as a dividend – Dividing 0 by any number results in a quotient of 0
0/ x = 0
digit – noun: any number from 0 to 9

The Cosine Rule – a² = b² + c² – 2bc.cosA – finding side
CosA = b² + c² – a² / 2bc – finding an angle
Tell how to find the probability that at least one of something will occur. – Use combination of the multiplication rule and the rule of complements to find the probability that at least one outcome of the element will occur. This given by the general formula p=1-p.
