There is not an order of computation - there is a commonly accepted convention for the order of computation, but , for example, most professional programmers would never rely on the fact that a "convention" was in use - and would force priorities with parentheses.
But the convention goes from exponentiation, to multiplication/divison (it's as arbitrary which comes first as the whole convention is, so I won't bother with the rest). And whatever rule you are looking for is bound to be incomplete. For example , will it show the priority of Logarithms? eg is Log 2 * 3 saying 3 times the log of 2, or is it the log of 6? and there's more but you get the idea (I hope)

PEMDAS-Please Excuse My Dear Aunt Sally
Parenthesis, Exponents, Multiply, Divide, Add, Subtract

According to what I have been taught the order of computation in mathematical problems is as below:
First do what is in the Brackets
Then, the Exponents (i.e. the indices)
Then, Divide
Multiply
Add (Addition)
The last being Subtraction.
Hence the acronym being BEDMAS

Parenthesis, exponent, multiplication/division, addition subtraction.

Are you refering to the order of operations or the FOIL method?
Order of Operations:
"Please Excuse My Dear Aunt Sally"
P = Parenthesis
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
The Foil Method is the following:
(w+x) (y+z)
First = w times y
Outer = w times z
Inner = x times y
Last = x times z

generally computation inside braces () is performed first,
outside of braces usual order be multiplication, addition, subtraction/devision (could be the other way round on last two)

I use My Dear Aunt Sally - multiplication, division, addition, subtraction -not sure what kind of equations you mean

PEMDAS: Parenthesis, Exponents, Multiplacation or Division (which ever is first left to right), Addition or Subtraction (again, left to right)

Parentheses
Exponents
Multipication/Division
Addition/Subtraction
PEMDAS (duh)
In the case of M/D and A/S they are treated as one function. In a problem they are processed left to right (Multipication does not take precedence over Division)
