We'll answer this generally, since you haven't provided an expression. A common technique for remembering the order of operations is the abbreviation "PEMDAS", which is turned into the phrase "Please Excuse My Dear Aunt Sally". It stands for "Parentheses, Exponents, Multiplication and Division, and Addition and Subtraction".

The rules for simplifying an algebraic or numerical expression?
There are a few rules for simplifying an algebraic expression. Specifically, one should combine like terms, and then they should try to isolate the variable by doing the opposite, either multiplication or division.
Who is the first person invent pemdas?
There is no known origin of the order of operations or PEMDAS. PEMDAS is considered as the proper way to tackle a given mathematical expression in terms of what operation should be performed first.
What is an expression that have the same value?

Which operation should be performed first according to the order of operations?
In a standard calculation it would be the exponent, also known as the power of. However, the use of brackets can change the order of operations and so sometimes another operation could be done first. Exponents should be processed first, then multiplication and division, then addition and subtraction. The use of parenthesis brackets can be used to override this default precedence order.
What is the algebraic expression for four divided by the difference between a number?
You don't have the complete question here. "...between a number" and what? First figure out what operation is being used, and then put that operation in the place of the "and" in the statement. Since difference is subtraction, you will put a minus sign in place of the "and" that should be after the word, "number." So, your answer will be as follows: 4/(x - ___) Fill in the blank with what ever is says after the word, "number,"
