Study Notes

Algebraic Operations

BIDMAS (Order of Operations) is a rule to follow when working with integers, fractions, and decimals.
It stands for Brackets, Indices, Division, Multiplication, Addition, and Subtraction.

Simplifying Expressions

Collecting like terms is a process of combining terms with the same variable and coefficient.
It is essential in algebraic operations, especially in multiplication and division.

Brackets and Formulae

Single brackets are used to group numbers and variables to follow the order of operations.
Constructing formulae involves using variables and constants to represent real-world problems.

Factorising

Factorising linear expressions is a process of expressing an algebraic expression as a product of simpler expressions.
It is used to simplify complex algebraic expressions.
