What is the set of rules that tell which operation to perform first when more than one operation is present in an expression?

The rules are commonly taught as BIDMAS (UK) or PEMDAS (US). I am not sure about other English speaking countries, and clearly non-English speakers will use other acronyms.
However, these acronyms are misleading since they would suggest that in the UK D comes before M whereas in the US M comes before D. In fact there are two pairs with equal priorities: D = M and A = S where the operations are performed from left to right.
The acronyms stand for
- B = Brackets ............................ P = Parentheses
- I = Index ................................... E = Exponent
- D = Division and M = Multiplication (equal priority, evaluate from L to R)
- A = Addition and S = Subtraction (equal priority, evaluate from L to R).
An alternative form in the UK is BODMAS where the O stands for "Order" (as in the size of an index) or "Of" (as in "10 percent of 56" where is means the same as multiply, but has a higher priority).

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.
Does it matter in which order we do each operation?
Yea because the collection of rules that define which procedures to perform first order to evaluate a given mathematical expression.
What can you use to control the order of operation in a formula?
The use of parentheses allows you to control, or change, the regular order of operations. For example, if you have the expression 4 + 2 * 3, under the normal order of operations, you would perform the multiplication before the addition. To perform the addition first, you just add parenthesis so the expression reads (4 + 2) * 3 instead.
What is the effect of inserting parentheses into a numerical expression?
It assures that whatever operation is contained within the parentheses will be carried out first.
The rules that tell which operation to perform first when more than one operation is used?
BIDMAS B = Brackets I = Index D = Division M = Multiplication A = Addition S = Subtraction

How do you evaluate an expression with more than two operation symbol without exponent and parenthesis?
In Evaluating Expression first,replace each letter in the expression with the assigned value. second,perform the operations in the expression using the correct order of operations and the last you got the answer

Are the symbols used to show which operation or operations in an expression should be done first?
parentheses
Write two order-of-operation problems?
The two orders of operation are: Perform all calculations inside the parentheses first. Perform all multiplication and division starting from left to right.
What is the effect of inserting parentheses into a numerical expression?
It assures that whatever operation is contained within the parentheses will be carried out first.
When simplifying an expression you a always b sometimes c never perform operations inside grouping symbols first?
A
How does the microprocessor knows which operation to perform first read or write?
in any of the microprocessor include sequencer that sequencer send control signal to the memory and processor to do specific operation like read or write operation
What is sixteen times 2 square?
Assuming no parenthesis, perform the exponential operation first, then perform the multiplication. 16 x 22 = 16 x 4 = 64
When simplifying an expression do you always perform operations inside grouping symbols first?
It's possible to perform other operations first. But if you try it, there's a muchbigger chance that you'll get all tangled up and your result will be wrong.
The rules that tell which operation to perform first when more than one operation is used?
BIDMAS B = Brackets I = Index D = Division M = Multiplication A = Addition S = Subtraction
