The Four Fundamental Operations (Addition, Multiplication, Subtraction and Division) form the basis of the whole study of mathematics and numerical science. These operations form all the other operations that we use in the above specified subjects. So they are called Fundamental Operations Because the can't be derived either in the terms of themselves or any other operator.
I am not sure there are any fundamental operations of integers. The fundamental operations of arithmetic are addition, subtraction, multiplication and division. However, the set of integers is not closed with respect to division: that is, the division of one integer by another does not necessarily result in an integer.
It follows from the definitions of the two operations.
Here are the operations that can be done with fractions: -- add two or more of them -- subtract one from another -- multiply two of them -- divide one by another -- raise one to a power -- find a root of one Pretty much the same operations that you can perform on any other number.
Any operation where the input is not two quantities. For example, Doubling a number is a unitary operation. Averaging 5 numbers is a 5-ary operation (sorry don't know what its called).
