Formal Pronunciation of PEMDAS
When it comes to formal settings, such as classroom discussions or professional environments, it is commonly accepted to pronounce PEMDAS as follows:
1. Parentheses: pronounced as “paren-THAY-sees”
2. Exponents: pronounced as “ex-POH-nents”
3. Multiplication: pronounced as “mul-ti-pli-KAY-shun”
4. Division: pronounced as “dih-VIH-zhun”
5. Addition: pronounced as “uh-DIH-shun”
6. Subtraction: pronounced as “sub-TRAK-shun”
It’s important to note that emphasizing the syllables in uppercase helps convey the intended meaning and avoid confusion.
Informal Pronunciation of PEMDAS
Outside of formal settings, especially among students and casual conversations, you might come across alternate pronunciations of PEMDAS. While they may not be academically endorsed, they’ve gained popularity and are worth mentioning:
1. Please Excuse My Dear Aunt Sally: This mnemonic phrase represents each letter of PEMDAS and provides an informal way to remember the order of operations. It is most commonly pronounced as “pleez ex-KYOOS my deer aunt SAL-ee.”
2. Parentheses, Exponents, Multiply, Divide, Add, Subtract: Often pronounced simply as “pem-das” or “pee-em-das,” this form reflects the order of operations using a phonetic approach.
While these informal pronunciations are widely recognized, it’s essential to understand that they may not be universally understood in all contexts. For formal or standardized discussions, reverting to the formal pronunciation of PEMDAS is advisable.
Examples and Tips for Using PEMDAS
Now that we’ve explored the different ways to say PEMDAS, let’s solidify your understanding by providing examples and helpful tips for utilizing the order of operations in mathematical expressions:
Example 1: Basic PEMDAS Usage
Consider the expression: 6 + (4 × 2) – 3
By following the order of operations:
- Start with the parentheses: 4 × 2 = 8
- Next, perform the multiplication: 6 + 8 – 3
- Finally, complete the addition and subtraction: 14 – 3 = 11
The result is 11.
Tip 1: Using PEMDAS to Clarify Ambiguous Expressions
PEMDAS is especially useful when dealing with complex expressions, where the order of operations helps resolve ambiguity. For example:
4 + 2 × 3
Here, by following PEMDAS, we perform the multiplication before addition:
- Multiply first: 2 × 3 = 6
- The final calculation: 4 + 6 = 10
If we didn’t follow the order of operations, the result would be incorrect.
Tip 2: Breaking Down Complex Expressions
When an expression includes multiple levels of parentheses, exponents, and operators, it’s helpful to visually break it down according to PEMDAS. Consider:
(((3 + 2) × 6²) ÷ 4)
- Solve innermost parentheses: 3 + 2 = 5
- Resolve exponents: 6² = 36
- Perform the multiplication: 5 × 36 = 180
- Finally, divide by 4: 180 ÷ 4 = 45
The expression evaluates to 45.
Tip 3: Remembering PEMDAS
Use mnemonic devices such as “Please Excuse My Dear Aunt Sally” or create your phrases to help remember the components and order of PEMDAS. Visual aids, like diagrams or charts, can also enhance your understanding and retention.
By practicing these tips and understanding the correct pronunciation, you’ll become proficient in applying PEMDAS to various mathematical calculations.
Conclusion
