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 operation should be performed first to solve this expression?
To determine which operation should be performed first in an expression, you should follow the order of operations, often remembered by the acronym PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)). First, check for any calculations within parentheses; if none exist, look for any exponents, then proceed to multiplication or division before finally handling addition or subtraction. Always work from left to right within the same level of the hierarchy.
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.
When you write a numerical expression how do you show what operation to do first?
In a numerical expression, the order of operations is indicated using parentheses to group terms, which shows what should be calculated first. According to the standard order of operations (often remembered by the acronym PEMDAS: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)), calculations inside parentheses are performed before any other operations. Additionally, using exponents clearly indicates that those calculations should be done prior to multiplication, division, addition, or subtraction.
Which options could be the next step in simplifying this expression?
I suggest that the next step should be identifying "this" expression.

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.

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.
