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.
How do you know when to simplify?
You should consider simplifying when a problem or expression appears overly complex or when you notice opportunities to reduce terms or factors. Look for common factors, like terms, or opportunities to use mathematical properties to make calculations easier. Additionally, if a solution path seems convoluted or if you're struggling to proceed, simplifying can help clarify your thinking and reveal the next steps.
Does multiplication always be done before division?
No, multiplication does not always have to be done before division; they are performed from left to right based on their appearance in an expression. According to the order of operations (PEMDAS/BODMAS), multiplication and division are of equal precedence and are executed in the order they occur. Therefore, if division comes before multiplication in a mathematical expression, it should be performed first.

To solve this expression, which operation should be performed second[21-(5+2)]^(2)*3?
subtract 7 from 21
What operation should be performed first a expression?
Expressions within parenthases (brackets) should be done first. Then each operation should be done in turn from left to right. Therefore 4+7x(5+4) would be 4+7x9 and then 11x9 =99.

Are the symbols used to show which operation or operations in an expression should be done first?
parentheses
What does cancel where possible mean in math?
That means that wherever you spot a numerator and denominator that have a common factor,you should should divide the numerator and denominator by their common factor.This operation doesn't change the value of an expression, but it 'simplifies' it. The operation isalso the heart and soul of measurement-unit conversions.It means that if you spot a numerator and denominator that have a common factor, then you should divide the numerator and denominator by their common factor.This operation doesn't change the value of an expression, but it 'simplifies' it. The operation is also the heart and soul of measurement-unit conversions.It means, if you can cancel, cancel. Otherwise don't.This usually refers to simplifying fractions that involve numbers or variables. If the same variable, or factor, appears in the top and in the bottom, you can eliminate it from both without changing the result.
