Does anyone have another way of memorizing the order of operations?

Question

Don't give me the one with Please Excuse My Dear Aunt Sally, ok. Please respond soon because I need one immediately if you can help. Thank-you.

Answer 1

I learned it as BEDMAS:

Brackets

Exponents

Division

Multiplication

Addition

Subtraction

Of course, division and multiplication can go in either order, the same is true for addition and subtraction.

Answer 2

just think of it as PEMDAS.... thats all I did

or come up with another thing like...

pete eats many dead aliens, suprisingly

Answer 3

Put every meal dining

after saturday

Answer 4

The Order of operations is a mathematical and Algebraic concept. It is used to simplify expressions and equations. The Order of operations defines the order in which different operations should be simplified. It is used for operations such as addition, subtraction, multiplication and division. It is critical to the solution of equations or expressions in the mathematics world.

In many math problems, people will have to solve more than one operation in order to get the answer. Mathematicians have agreed on a correct order to perform these operations, and it is very important that they know these rules. Whenever people are solving a problem with more than one operation, they will need to know the correct order in which to solve the problem. Rules for solving problems with multiple operation signs; addition, subtraction, multiplication, division and grouping symbols; parentheses or brackets are as follows:

First, working left to right solve any math operations within parentheses and change any exponential notations to standard notations.

Next, again starting on the left and working right, across the problem, solve any multiplication and division in the problem.

Lastly, and always lastly, working again from left to right solve any addition or subtraction left in the problem.

The result is the answer to the problem.

Example: 12 – 2²(9 – 6) + 5 ÷ 5

First … Parenthesis and Exponent … what ever comes first as the person works from left to right.

12 – 2²(9 – 6) + 5 ÷ 5

= 12 – 4(9 – 6) + 5 ÷ 5

= 12 – 4(3) + 5 ÷ 5

Once they have solved the operations within the parentheses they are no longer being used to define a grouping to do first, but now stand for multiplication.

Second … Multiplication and Division … what ever comes first as they work from left to right.

12 – 4(3) + 5 ÷ 5

= 12 – 12 + 5 ÷ 5

= 12 – 12 + 1

Third and lastly … Addition and Subtraction … what ever comes first as they work from left to right.

12 – 12 + 1

= 0 + 1

= 1

The answer to the problem.

12 – 2²(9 – 6) + 5 ÷ 5 = 1

A good way to remember the Order of Operations is by memorizing the phrase “Please Excuse My Dear Aunt Sarah”. The first letter of each word of this phrase is key in remembering the order.

P = Parentheses

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subtraction

Memorizing the phrase “Please Excuse My Dear Aunt Sarah” will help people remember the Order of Operations.

Another good way of memorizing the Order of Operations is the word BIMDAS. The letters of the word represent the first letters of each word in the order of operations.

B stands for Brackets

I stands for Indices (indices are the same as exponents)

M stands for Multiplication

D stands for Division

A stands for Addition

S stands for Subtraction
