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.

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.
Which arithmetic operation will performed first if there is Multiplication and division in a formula with no parentheses?
In an expression with both multiplication and division and no parentheses, the operations are performed from left to right. This means that if multiplication comes before division, it will be executed first, and vice versa. Essentially, the order in which these operations appear in the expression determines their sequence of execution.
Which operation should be performed first when simplifying the expression?
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".
How do you evaluate a math expression?
The evaluate a algebraic math expression you first must substitute a number for each variable. Then you must perform the operation in the correct order.
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.
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.

Multiplications and divisions from left to right.
