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.
