The correct order of operations in math is Parentheses, Exponents, Multiplication and Division (from left to right), followed by Addition and Subtraction (from left to right). This is also known as the “PEMDAS” rule, which stands for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction.
It is important to remember and follow the correct order of operations because it affects the final answer of a mathematical problem. Without following and understanding the correct order of operations, you are more likely to come up with the wrong answer when attempting to solve a problem.

Which math operation comes first?
The order of operations is an important concept in mathematics. It states that certain operations must be performed before others in order to get the correct answer. The acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) is commonly used to remember the order math operations must be performed in:
1. Parentheses: Any operations inside parentheses should be completed first.
2. Exponents: Then, all exponents should be evaluated.
3. Multiplication and Division: These operations should be completed in order from left to right.
4. Addition and Subtraction: These should be completed in order from left to right.
It is important to note that another acronym, BODMAS (Brackets, Orders, Division, Multiplication, Addition, Subtraction), is also occasionally used in some countries. The main difference between the two acronyms is that BODMAS implies that operations within brackets should be performed first, while PEMDAS states that operations within parentheses should be performed first.
Which is first multiplication or addition?
The answer to this question is that it depends on the circumstances. Generally speaking, addition is the simpler of the two operations, as it requires only counting the number of objects represented.
Multiplication, on the other hand, requires more complex calculations.
When introducing mathematics to young children, addition is typically taught before multiplication. This helps to ensure that basic counting skills are learned before the more complex concepts of multiplication begin to be covered.
In other situations, it might make more sense to begin with multiplication. For example, when studying more advanced mathematics, the order in which different operations are introduced may depend on the type of problem being discussed.
In this case, it may make sense to introduce multiplication first as it is a key part of solving many equations.
Regardless of which is taught first, it is important to remember that both addition and multiplication are fundamental operations that need to be understood in order to understand advanced mathematics.
Do you multiply first if no brackets?
Yes, when there’s no brackets, you should always multiply first. This is because multiplication and division are the two operations you should do first in an equation. However, it is important to remember that the operations should always be done in the order of Parentheses, Exponents, Multiplication and Division, and finally Addition and Subtraction.
If you are working with both multiplication and division in an equation, you should refer to the order of operations to ensure your equation is solved correctly.
Which is correct Pemdas or Bodmas?
PEMDAS and BODMAS are both acronyms that represent the Order of Operations, which is the order in which operations (such as addition, subtraction, multiplication and division) should be performed when evaluating an expression.
They are both correct, though PEMDAS is more commonly used in the United States while BODMAS is more commonly used in other countries. In essence, they both stand for the same thing: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
What is the MDAS rule in math?
The MDAS rule in math is a helpful way to remember the correct order in which to perform mathematical operations. The acronym “MDAS” stands for “Multiplication, Division, Addition, and Subtraction”, and expresses the order of operations that should be used when doing operations within one problem.
The order should always be followed, as it helps to ensure that the problem is solved correctly. Multiplication and Division should be done first, from left to right, followed by Addition and Subtraction, also from left to right.
For example, if an equation reads: 6 + 4 x 7
The correct way to solve this equation is to first multiply 4 and 7 together to get 28, then add 6 and 28 together to get the answer of 34. If the equation were written as 6 x 4 + 7, then the correct order of operations would be to multiply 6 and 4 first, then add 7 to the answer.
It is important to remember the MDAS rule, as it will help to get accurate results while solving math problems.
Is Pemdas wrong?
No, PEMDAS (or sometimes called the “Order of Operations”) is not wrong. It is simply a guideline and tool used to provide a consistent process for evaluating and solving mathematical equations. PEMDAS is an acronym which stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction.
These steps are then used to solve equations, such as integers or equations with multiple operations, and help guide the user to a correct solution. Despite the usefulness of PEMDAS as a tool and guideline, it is important to always double check results as errors can still be made if the steps are applied incorrectly.
What is the correct answer to 8 2 2 2?
The correct answer to 8 2 2 2 is 12. This can be solved by performing the following mathematical operation: 8 + 2 + 2 + 2 = 12.
What replaced Pemdas?
Pemdas is an acronym used to help people remember the order of operations when solving a mathematical problem. Pemdas stands for parentheses, exponents, multiplication/division, addition/subtraction.
This acronym has been widely accepted and used for many years, but it has recently been replaced with the acronym Bedmas.
Bedmas stands for brackets, exponents, division, multiplication, addition, subtraction. This acronym puts brackets and exponents as the first two steps in a mathematical problem, which makes perfect sense since these are the operations that must be completed first in any mathematical equation.
The order of operations for Bedmas is the same as for Pemdas, but the acronym allows for a greater level of clarity, since the steps are broken into symbols and numbers. This can help people more easily understand the order of operations and make it easier to remember.
Is Pemdas and Pemdas the same?
No, PEMDAS and BEDMAS are not the same. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction while BEDMAS stands for Brackets, Exponents, Division, Multiplication, Addition, and Subtraction.
The order PEMDAS emphasizes the importance of parentheses and follows the order of operations, ensuring that all operations within parentheses are completed first before proceeding with the other operations.
The order BEDMAS places emphasized importance on brackets, allowing for operations within brackets to be completed first before continuing with the rest.
Is Pemdas always correct?
No, Pemdas is not always correct. Pemdas stands for “Please Excuse My Dear Aunt Sally” and it is a common acronym used to help remember the order of operations in mathematics. It stands for parentheses, exponents, multiplication and division, addition and subtraction.
The Pemdas approach to solving math problems is a great tool for basic equations, but it is important to remember that there are situations where the order of operations might be different. For example, when both multiplication and division appear in a single equation, it might be best to do the division first, rather than following the conventional Pemdas approach.
Additionally, there are more complex problems that will require a different approach altogether, such as integration or differentiation. In these cases, Pemdas is not always correct.
Has Pemdas been replaced?
No, Pemdas has not been replaced by anything. Pemdas stands for Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction. It is a mnemonic used to help students remember the order of operations when solving math problems.
While there are other methods to solve math problems, such as using a number line, Pemdas is typically the go-to order of operations when trying to solve math problems. It is a simple and reliable way to stay organized when doing math and has been used for decades.
Is there an exception to Pemdas?
No, PEMDAS stands for “Please Excuse My Dear Aunt Sally” and is essentially a set of rules that provides a specific order of operations when solving mathematical problems. As such, there is no exception to this rule.
The acronym is used to remind students that they should first do any calculations within parentheses, then exponential calculations, followed by multiplications and divisions (from left to right), then additions and subtractions (also from left to right).
There is always an order to the calculations being performed, and because it is a rule, there cannot be an exception.
Does it matter if you multiply or divide first in Pemdas?
Yes, it does matter whether you multiply or divide first in Pemdas. The order of operations, or Pemdas, provides a standard convention when solving mathematical equations. The acronym stands for parentheses, exponents, multiplication, division, addition, and subtraction.
Following this order of operations ensures that you will get the same answer regardless of which order you choose to calculate your equation. When it comes to multiplication and division, Pemdas states that you should solve these operations in the order that they appear from left to right.
This means in order for you to get the correct answer for an equation, it’s important to recognize the specific order that the equation should be solved in. Ignoring or reversing the order of operations can lead to incorrect results.
Why do Americans use Pemdas?
Pemdas, short for Parentheses, Exponents, Multiplication and Division, Addition and Subtraction, is a mnemonic device used primarily in the United States to help people remember the order of operations in mathematics.
By following the steps of Pemdas, one can ensure that they solve the math problem correctly. American students are taught Pemdas so that they can solve all kinds of math problems, from simple addition and subtraction, all the way through advanced calculus.
Not only does Pemdas help students understand the order of operations in mathematics, but it also helps them become more independent learners and thinkers. By learning Pemdas, students learn to do mathematics on their own and develop problem-solving skills.
Having an understanding of Pemdas is important for students to succeed in math because it helps them to work through challenging equations and understand the different operations. It can be especially useful when solving equations with multiple operations, and it supports students in developing the ability to think logically and systematically, which is a great skill to have regardless of the subject.
