The order of operations is a law for solving math problems with multiple operations in mathematics like adding, subtracting, multiplying, and division. Many people use a popular mnemonic known as PEMDAS as a memory aid for recalling the order of operations while studying math and learning how to use it correctly.
- P – Parentheses
- E – Exponents
- MD- Multiplication and Division
- AS – Addition and Subtraction
PEMDAS Key Ideas:
PEMDAS rule has been around for a long time, and many math students use the expression “Please Excuse My Dear Aunt Sally” to recall the order of operations in math. PEMDAS isn’t a perfect mnemonic for understanding how to execute the proper sequence of operations, but it can be a valuable method if you recall a few key details:
- Always start with the brackets or groups if there.
- Exponents always come after brackets and groupings.
- Perform multiplication and division after brackets and exponents, whichever comes first moving from left to right.
- Perform addition or subtraction after multiplication and division, whichever comes first moving from left to right.
Importance of PEMDAS
Due to the importance of math problems that pop up in our day-to-day activities, the use of applying the order of operations and using PEMDAS has become very common in recent years. People believe that the correct way to apply the order of operations is to operate from left to right, so these types of mathematical equations are common. Since the majority of people get these basic math problems wrong, they are enlightening and show the importance of PEMDAS. However, if people can recall the order of operations using a mnemonic like PEMDAS or even another effective one, and understand the complexities of correctly applying the order of operations, namely the relationship between multiplication or division and addition or subtraction, these kinds of mathematical problems could be solved quickly and without much confusion or inaccuracy.
The Operational Rules for PEMDAS
The PEMDAS rule tells us how to solve a numerical expression in the correct order. Operations are done in brackets at the start of the PEMDAS procedure. After that, operations on exponents and powers are performed. This is followed by multiplication or division operations from left to right, whichever comes the earliest. Finally, addition and subtraction operations are solved from left to right, whichever comes the earliest.
It’s difficult to solve math problems correctly both basic and complex, without knowing how to apply the math order of operations, and PEMDAS is a useful tool for remembering them in the correct order, as long as you remember the relevant sub-rules mentioned above. PEMDAS may not be the only way to remember how to use the math order of operations correctly, but it can be a useful guide if you remember the main sub-rules as well. PEMDAS is also known as BODMAS. Both terms might be different but have the same meaning.
How can you make learning PEMDAS interesting?
Use Flashcards and Quizzes
Making flashcards will help you recall the things you have learned. Flashcards are a fast and easy way to test your understanding of a topic. Quizzes are the digital version of flashcards. You can also create assessments and memorization games in addition to flashcards to make it fun and engaging. Flashcards and quizzes are the best way to interact with children on an educational topic. This will not only teach them but will also enhance their conversational skills.
If you love math, consider making an acronym out of the first letters of your most important terms, such as PEMDAS in math that is parentheses, exponents, multiplication, division, addition, and subtraction. Make up a word, like the four P’s of Marketing, if an acronym does not work for you. Using acronyms will make you remember the operational rules as well which are the bases of PEMDAS.
