How to Remember the Order of Operations
The order of operations is a fundamental concept in mathematics that ensures calculations are performed in the correct sequence. It is crucial for students to understand and remember this order to avoid errors in their calculations. The order of operations is commonly remembered using the acronym PEMDAS, which stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). In this article, we will discuss various strategies to help you remember the order of operations.
1. Use PEMDAS as a Mnemonic
The most straightforward way to remember the order of operations is by using the PEMDAS acronym. Break down each letter to help you recall the sequence:
– Parentheses: First, solve any calculations within parentheses.
– Exponents: Next, evaluate any exponents or powers.
– Multiplication and Division: Perform multiplication and division from left to right, regardless of their order in the expression.
– Addition and Subtraction: Finally, perform addition and subtraction from left to right, regardless of their order in the expression.
By memorizing the PEMDAS acronym and understanding what each letter represents, you can easily recall the order of operations.
2. Create a Story or Rhyme
Another effective method to remember the order of operations is by creating a story or rhyme that incorporates the letters of PEMDAS. For example:
“Please Excuse My Dear Aunt Sally”
This rhyme helps you remember the order of operations as follows:
– “Please” stands for Parentheses.
– “Excuse” stands for Exponents.
– “My” stands for Multiplication and Division.
– “Dear” stands for Addition and Subtraction.
– “Aunt” stands for Addition and Subtraction.
– “Sally” stands for Addition and Subtraction.
By repeating this rhyme, you can easily recall the order of operations.
3. Practice with Examples
One of the best ways to remember the order of operations is by practicing with various examples. Work through problems that involve parentheses, exponents, multiplication, division, addition, and subtraction. As you solve these problems, pay close attention to the order in which you perform the calculations. This will help you internalize the order of operations and make it second nature.
4. Use a Memory Aid
If you struggle to remember the order of operations, consider using a memory aid, such as a visual representation or a physical object. For instance, you can create a PEMDAS chart and place it near your study area. Alternatively, you can create a small PEMDAS reminder card that you can carry with you.
5. Review Regularly
Finally, to ensure that you retain the order of operations, review it regularly. Consistent practice and repetition will help you remember the sequence and apply it accurately in your calculations.
In conclusion, the order of operations is a vital concept in mathematics. By using mnemonic devices, creating stories or rhymes, practicing with examples, using memory aids, and reviewing regularly, you can effectively remember the order of operations and perform calculations with confidence.
