A math operation is a question involving numbers and/or numerals.
* * * * *
An operation is a rule according to which two (or more) numbers (or variables) are combined to form another number (or variable). The numbers or variables need not all be different.
Addition. subtraction, multiplication and division are common binary operations. The word "binary" means that they are rules about combining two variables to form a third. In many cases, a binary operation can be applied again and again so that adding together of a lot of numbers does not appear to be binary.

An operator is a rule for combining or transforming numbers.
For example, the four primary operators of arithmetic ( +, - , * , / ) are binary operators and they describe the rules for combining two numbers to give a third number as the answer.
Square root or reciprocal are examples of unary operators which transform one number into another.
The validity of operators may be restricted by their domain or range. Division is not defined if the second number is 0. Square roots of negative numbers are not defined unless the range is the complex field.
There is no "power" operator in C or C++. You need to the use the math library function pow().
6 = - 17 is a false statement However, it may mean that an operator is missing so that the numbers have run together. 6 = (-1) + 7 By putting the operator + between the numbers -1 and 7, it becomes a true statement.
Lots and lots and lots. Just off the top of my head, anything that uses quantum physics is based off of Hilbert space theory and operator analysis, which are both (older) fields of math.
how does a scale operator make
The hamiltonian operator is the observable corresponding to the total energy of the system. As with all observables it is given by a hermitian or self adjoint operator. This is true whether the hamiltonian is limited to momentum or contains potential.
