Order of Operations: PEMDAS/BODMAS ensures consistent results by dictating the order of operations: Parentheses/Brackets, Exponents/Orders, Multiplication and Division, Addition and Subtraction.
Properties of Numbers: Commutative (changing order doesn't affect outcome), Associative (grouping doesn't affect outcome), Distributive (multiplication distributed across addition).
Factorization: Breaking down numbers into their factors helps understand their composition.

Area Formulas:
- Rectangle: Area (A) equals length (l) multiplied by width (w): A = l × w
- Triangle: Area (A) equals half the base (b) multiplied by the height (h): A = 1/2 × b × h
- Circle: Area (A) equals pi (π) multiplied by the square of the radius (r): A = πr²
Volume Formulas:
- Cube: Volume (V) equals the cube of the side length (s): V = s³
- Rectangular prism: Volume (V) equals length (l) multiplied by width (w) multiplied by height (h): V = l × w × h
- Cylinder: Volume (V) equals pi (π) multiplied by the square of the radius (r) multiplied by the height (h): V = πr²h
