The order of operations, often remembered by the acronym PEMDAS/BODMAS, is crucial in mathematics. This article provides a thorough explanation of the order of operations, focusing specifically on problems involving exponents, and includes a downloadable PDF worksheet for practice. Mastering the order of operations with exponents is fundamental for success in algebra and beyond.

Understanding the Order of Operations (PEMDAS/BODMAS)

The order of operations dictates the sequence in which calculations should be performed within a mathematical expression. The acronyms PEMDAS and BODMAS represent the same order, just with slightly different wording:

• Parentheses/Brackets: Perform operations inside parentheses or brackets first.
• Exponents/Orders: Evaluate exponents (powers) next.
• Multiplication and Division: Perform multiplication and division from left to right.
• Addition and Subtraction: Perform addition and subtraction from left to right.

Remember: Multiplication and division have equal precedence, as do addition and subtraction. You perform these operations from left to right as they appear in the expression.

Order of Operations with Exponents: Examples

Let's illustrate the order of operations with examples emphasizing exponents:

Example 1:

3 + 2² × 5 - 4

1. Exponents: 2² = 4. The expression becomes 3 + 4 × 5 - 4.
2. Multiplication: 4 × 5 = 20. The expression becomes 3 + 20 - 4.
3. Addition and Subtraction (left to right): 3 + 20 = 23; 23 - 4 = 19.

Therefore, the answer is 19.

Example 2:

(10 - 2)² ÷ 4 + 6 × 3

1. Parentheses: 10 - 2 = 8. The expression becomes 8² ÷ 4 + 6 × 3.
2. Exponents: 8² = 64. The expression becomes 64 ÷ 4 + 6 × 3.
3. Division and Multiplication (left to right): 64 ÷ 4 = 16; 6 × 3 = 18. The expression becomes 16 + 18.
4. Addition: 16 + 18 = 34.

Therefore, the answer is 34.

Example 3: Incorporating Negative Exponents

-2 + 3 * 2⁻² + 5

1. Exponents: 2⁻² = 1/2² = 1/4 = 0.25
2. Multiplication: 3 * 0.25 = 0.75
3. Addition: -2 + 0.75 + 5 = 3.75

Therefore, the answer is 3.75.

Common Mistakes to Avoid

A frequent error is performing operations out of order. Always strictly adhere to PEMDAS/BODMAS to avoid incorrect results. Another common mistake involves misinterpreting exponents, particularly with negative exponents or those involving fractions.
