The Bodamas Rule of Mathematics is a mathematical formula, it simplifies the process of solving equations and is applicable to multiple types of math problems. Learn how to apply Bodamas Rule and how it can help you solve more complex equations.
Table of Contents
An arithmetic expression sequence of operations is known as BODMAS, or the order of operations. Math is about rationale and a few standard guidelines that make our computations simpler. As a result, BODMAS is a well-known rule for simplifying expressions with multiple operators.
What is BODMAS Rule
To understand the BOADMAS rule, first learn about the abbreviation for BODMA, which is Bracket, Of, Division, Multiplication, Addition, and Subtraction. The mathematical expression order of the operation can be explained with the help of BODMAS. PEDMAS, which stands for Parentheses, Exponents, Division, Multiplication, Addition, and Subtraction, is another name for the BODMAS that is used in some areas.
Example Question Using BODMAS Rule:
Question 1: (4+5)-3+2
Solution: (9)-3+2
Now, an addition has to be solved:
(9)-5 = 4
When is BODMAS Useful
When there are multiple operations in a mathematical expression, BODMAS rule is used. When using the BODMAS method, certain rules must be followed in a certain order. This provides an appropriate structure for coming up with a unique response to each mathematical expression.
Conditions to follow:
Open any bracket, then add or subtract the terms from them.
a + (b + c) = a + b + c, a + (b - c) = a + b - c.
If there is a negative sign, simply open the bracket and multiply the negative sign by each term inside the bracket.
a - (b + c) a - b - c
Multiply any term that is just outside the bracket by each term that is inside the bracket.
ab + ac = a(b + c)
Simple Rules for Remembering the BODMAS Rule
To understand and memorise the BODMAS rule, there are a few basic rules or conditions given in the table below that need to be cleared and it makes the learning and understanding process of BODMAS rule easier
| Condition | Rule |
| x + (y + z) ⇒ x + y + z | Open the bracket and add the terms. |
| x – (y + z) ⇒ x – y – z | Open the bracket and multiply the negative sign with each term inside the bracket.(All positive terms will be negative and vice-versa) |
| x(y + z) ⇒ xy + xz | Multiply the outside term with each term inside the bracket |
The following are some easy ways to remember the BODMAS rule
- First, simplify the brackets.
- Complete all exponential equations.
- Perform division or duplication (go from left to right)
- Perform expansion or deduction (go from left to right)
