Arithmetic Expression
A combination of numbers and basic mathematical operations like addition, subtraction, multiplication, and division.
BODMAS Rule
The standard order of operations: Brackets, Orders, Division, Multiplication, Addition, and Subtraction, which tells us which part of an expression to solve first.
Types of Brackets
Grouping symbols used in mathematics including parentheses (), curly brackets {}, and square brackets [], solved from the innermost outward.
Simplification
The process of reducing a complex arithmetic expression down to a single final number by performing operations in the correct order.

Frequently Asked Questions
What does BODMAS stand for?
BODMAS stands for Brackets, Orders (powers/roots), Division, Multiplication, Addition, and Subtraction, representing the exact sequence to solve math problems.
Which operation should I do first if both multiplication and division are in an expression?
You should perform multiplication and division from left to right as they appear in the expression.
Why do we need brackets in arithmetic expressions?
Brackets dictate which part of the expression must be calculated first, preventing ambiguity and ensuring everyone gets the same correct answer.
