Arithmetic Expression
A combination of numbers and basic mathematical operations (+, -, *, /) that produces a definite value when simplified.
BODMAS Rule
The order of operations used to simplify expressions: Brackets, Of, Division, Multiplication, Addition, and Subtraction.
Use of Brackets
Brackets like parentheses (), curly brackets {}, and square brackets [] are used to group parts of an expression that must be solved first.

Frequently Asked Questions
What does BODMAS stand for?
BODMAS stands for Brackets, Of, Division, Multiplication, Addition, and Subtraction. It tells us the exact order in which we must perform calculations.
Which operation should be done first if both multiplication and division are present?
Always solve multiplication and division from left to right as they appear in the expression.
Why do we use brackets in arithmetic expressions?
Brackets help to change the normal order of operations and clearly show which part of the expression needs to be calculated first.
