BODMAS Rules Overview

Study Notes

BODMAS Overview

BODMAS is an acronym that defines the order of operations in mathematics:
- Brackets
- Orders (i.e., powers and square roots, etc.)
- Division
- Multiplication
- Addition
- Subtraction

Division and Multiplication

Rule: Operations should be performed from left to right.
Importance:
- Both division and multiplication have the same level of priority.
- When encountered in an expression, perform them in the order they appear from left to right.

Example:

Expression: ( 8 \div 4 \times 2 )
- Calculation: Perform ( 8 \div 4 = 2 )
- Then, ( 2 \times 2 = 4 )

Addition and Subtraction

Rule: Like division and multiplication, addition and subtraction are performed from left to right.
Importance:
- Addition and subtraction also have the same level of priority.
- They are the final operations to be carried out in an expression.

Example:

Expression: ( 5 + 3 - 2 )
- Calculation: Perform ( 5 + 3 = 8 )
- Then, ( 8 - 2 = 6 )

Summary of Operations Order

Solve expressions within brackets first.
Handle any orders (exponents, roots, etc.).
Perform all divisions and multiplications from left to right.
Finally, perform all additions and subtractions from left to right.

Key Points

Follow BODMAS to ensure correct results in calculations.
Always handle operations of the same rank (division/multiplication, addition/subtraction) from left to right to avoid errors.

BODMAS Order of Operations

BODMAS is an acronym representing the order of operations in mathematics: Brackets, Orders, Division/Multiplication, Addition/Subtraction.

Division & Multiplication

Division and multiplication have equal priority in BODMAS.
When encountered together, calculations are performed from left to right.

Addition & Subtraction

Addition and subtraction also have equal priority in BODMAS.
When encountered together, calculations are performed from left to right.

Summary of BODMAS Rule

Solve expressions within brackets first.
Calculate any orders, such as exponents and roots, next.
Perform division and multiplication from left to right.
Finally, perform addition and subtraction from left to right.

Key Points

Following BODMAS ensures accurate calculations.
Completing operations of equal rank, such as division and multiplication, from left to right avoids errors.
