Have you ever encountered a math problem that left you puzzled because different people arrived at different answers? The key to consistent results lies in understanding the order of operations. Two commonly used acronyms that guide this process are BODMAS and PEMDAS. But are they truly different? Let’s unravel this mathematical mystery!
Decoding the Order of Operations
In mathematics, the sequence in which we perform operations is crucial to ensure consistency and accuracy. The order of operations provides a standardized approach, ensuring that everyone interprets and solves expressions uniformly.
The acronyms BODMAS and PEMDAS serve as mnemonic devices to help remember this sequence. Here’s what they stand for:
BODMAS (common in the UK and other Commonwealth countries):
- Brackets
- Orders (another term for exponents, including powers and roots)
- Division
- Multiplication
- Addition
- Subtraction
PEMDAS (widely used in the USA and some other regions)
- Parentheses
- Exponents
- Multiplication
- Division
- Addition
- Subtraction
At first, they might appear different, but in reality, they follow the same fundamental principles.
Do BODMAS and PEMDAS Yield Different Results?
Not at all! Despite the variation in terminology, both acronyms adhere to the same fundamental principles:
- Brackets/Parentheses: Solve expressions within these first.
- Orders/Exponents: Address exponents (powers and roots) next.
- Division and Multiplication: Perform these operations from left to right, whichever comes first.
- Addition and Subtraction: Finally, carry out these operations from left to right.
It’s important to note that multiplication and division are of equal precedence; they are performed sequentially from left to right, as they appear in the expression. The same applies to addition and subtraction. This left-to-right rule ensures consistency in solving expressions.
Example Expression:
(6+4)(exponent 2)÷5×3−8+12
Step-by-step solution using BODMAS/PEMDAS
- Brackets (B) / Parentheses (P)
(6+4)=10
Now, the expression becomes:
10 (exponent 2) ÷ 5 × 3 − 8 + 12 - Orders (O) / Exponents (E)
10 (exponent 2) =100
Now, the expression becomes:
100÷5×3−8+12 - Division (D) and Multiplication (M) (left to right)
100÷5=20
20×3=60
Now, the expression becomes:
60−8+12 - Addition (A) and Subtraction (S) (left to right)
60−8=52
52+12=64
The final answer is 64.
