What is the PEMDAS Rule in Grade 5 Maths?
FAQs on Order of Operations Practice Worksheet for Class 5 Maths (PEMDAS Rule)
1. What is the order of operations in PEMDAS for Grade 5?
In Grade 5 Maths, the order of operations follows the PEMDAS rule, which provides a clear sequence for solving expressions with multiple operations. Following this rule ensures you always get the correct answer.
The sequence is as follows:
- P - Parentheses: Solve all calculations inside (parentheses) first.
- E - Exponents: Next, calculate any exponents (e.g., 5²).
- MD - Multiplication and Division: Then, solve all multiplication and division from left to right as they appear.
- AS - Addition and Subtraction: Finally, solve all addition and subtraction from left to right.
2. What is the difference between PEMDAS and BODMAS?
PEMDAS and BODMAS are two acronyms for the exact same mathematical rule governing the order of operations; they just use different words for the same concepts. Both ensure that anyone solving a complex math problem will arrive at the same unique answer.
- PEMDAS stands for Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.
- BODMAS stands for Brackets, Orders (or Of), Division/Multiplication, Addition/Subtraction.
Here, 'Parentheses' and 'Brackets' are the same, and 'Exponents' and 'Orders' refer to the same operation.
3. How do you solve PEMDAS step by step?
To solve a problem using the PEMDAS rule, you must follow the sequence of operations precisely. This step-by-step method is essential for solving any mixed math expression correctly.
Here are the steps:
- Step 1 (Parentheses): Start by solving any calculations inside the parentheses.
- Step 2 (Exponents): After clearing the parentheses, calculate any terms with exponents.
- Step 3 (Multiplication and Division): Work from left to right, solving any multiplication or division problems as you encounter them.
- Step 4 (Addition and Subtraction): Finally, work from left to right again, solving any remaining addition or subtraction.
4. Why are the order of operations important in maths?
The order of operations is critically important in maths because it provides a universal standard that guarantees a single, correct answer for any given mathematical expression. Without a rule like PEMDAS, a problem could be interpreted in multiple ways, leading to different and incorrect answers.
For example, in the expression 5 + 2 × 3, the order of operations dictates that multiplication must be done before addition, giving the correct answer of 11. Without this rule, one might incorrectly calculate 5 + 2 first, resulting in 21.
