Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction (remember that multiplication and division occur at the same time starting at the left and moving right and the same is true of addition and subtraction. So the six letters: PEMDAS Which is commonly expressed as Please Excuse My Dear Aunt Sally or Purple Elephants Marching Down A Street.
In math, the Commutative Property refers to operations in which the order of the numbers being operated on does not matter. Multiplication and addition are commutative operations, which may be demonstrated by the algebraic equations "ab = ba" and "a + b = b + a", respectively.

Since the word MATH does not have any duplicated letters, the number of permutations of those letters is simply the number of permutations of 4 things taken 4 at a time, or 4 factorial, or 24.
In mathematics, the acronym PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). This order of operations should be used whenever you are solving an algebraic expression or equation to ensure that you arrive at the correct answer. By following the PEMDAS order, you can avoid errors and confusion in your calculations.
any number at all
You do it wrong. With out order of operations, the same math problem could have several different answers. In math, there is only one answer.
I want to know [what is the order of operations in math?]
fake
If the letters represent unknowns they are usually called variable.
Parentheses
Order of Operations
Variables. If you're talking about math.....
Math can be difficult at times. To simplify a math expression, it is important to follow the order of operations, or PEMDAS.
In many mathematical applications letters represent quantities that are being solved for and that are not initially known. There are also applications in computer science where calculations have to be made using math in base other than ten. For example hexadecimal numbers are sometimes used to locate a spot in a system dump in order to troubleshoot a problem. In hex arithmetic, letters A through F could represent 10 through 15, the number 10 equaling 16.
In a mathematial equation the letters wither represent a variable or a constant.
It is convenient for different people to agree on the standard order of operations. This saves complicated explanations.
