Worksheets on Order of Operations
In these lessons, we will learn the order of operations when calculating an expression with mixed operations.
BODMAS is an acronym that helps you remember the correct order of operations for solving a mathematical expression. When you see an equation with multiple different operations, following the BODMAS rule ensures you get the right answer every time.
The mnemonics BODMAS can be used to help us remember the order which is shown in the following table. Scroll down the page if you need more examples and explanation about BODMAS.

Brackets
You should always solve any part of the equation that is inside brackets first.
Orders
This refers to powers or indices, such as a number raised to a power.
Division and Multiplication
These two operations have the same priority. You should solve them from left to right, as they appear in the equation.
Addition and Subtraction
Like division and multiplication, these also have the same priority. Solve them from left to right, as they appear.
The following mnemonics are also used:
BIDMAS where I is for Indices
BEDMAS where E is for Exponents
PEMDAS where P is for Parenthesis

Order of Operations
In this video you’ll learn about one of the most important areas of number work - the order of operations. You’ll learn that the order in which we carry out any calculation is very important. This video describes a simple set of rules that make sure that anyone doing a calculation does so in the same way. You’ll see that these rules can be remembered really easily using the acronym BIDMAS, or BODMAS as it is also known.
BODMAS
This is the order in which you should do a maths equations.
First do anything in brackets.
Second, do any orders (these are squared, cubed, square root and the like).
Any multiplication or divide come next,
and finally do any addition or subtraction…left to right.
Order of Operations (BODMAS, BIDMAS, PEDMAS, PEMDAS)

BODMAS or BIDMAS
BODMAS - Do the (Brackets) first
BODMAS - Orders come after that
BODMAS - Divide or Multiply
BODMAS - Add or Subtract
A fun way of introducing the mathematical calculation convention, the BODMAS song.
