The basic rules of arithmetic and algebra apply in most cases. That is:
Exponentiation is done first
Multiplication and division are done next
Finally, addition and subtraction are done.
If two or more operations with the same priority appear together in the same expression, they're handled in left to right order. Parentheses can be used to override the order of operations; expressions in parens are evaluated first.
For example, 2*4**2 - 8/4 would be evaluated this way:
Do the exponent first: 4**2 = 16. The expression is then 2*16 - 8/4
Next do the multiplication and division: 2*16 = 32 and 8/4 = 2
Do the subtraction last: 32 - 2, or 30.
The only possible difference is in division, IF you're using computer rules for integer operations. Because a fully integer-based expression can only be expressed as another integer, computers perform integer division by truncating any fractional remainder of a quotient. So for example a computer would evaluate 7 / 2 = 3, rather than 3.5. If the numbers were expressed as real numbers the answer would be correct in the algebraic sense, though: 7. / 2. = 3.5

What are the rules for every operation in integers?
There are an infinite number of operations for integer and different rules will apply for different operations. The question needs to be more specific.
Rules to subtracting integers?
4/9 - 6/36
What are the rules in adding integers with like and unlike signs?
To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)
What is the difference between adding and multiplying integers?
They are different operations, giving different results. Example: 1+1=2, 1*1=1.
What is the integer rules?
The rules of integers state:~ two negatives make a positive number~one negative and one positive makes a negative number~ two positives are simply positive numbers
