A program may execute the same computations repeatedly. The program below repeatedly asks the user to enter an annual salary, stopping when the user enters 0 or less. For each annual salary, the program determines the tax rate and computes the tax to pay. 1. Run the program below with annual salaries of 40000, 90000, and then 0. 2. Modify the program to use a while loop inside the given while loop. The new inner loop should repeatedly ask the user to enter a salary deduction, stopping when the user enters a 0 or less. The deductions are summed and then subtracted from the annual income, giving an adjusted gross income. The tax rate is then calculated from the adjusted gross income. 3. Run the program with the following input: 40000, 7000, 2000, 0, and 0. Note that the 7000 and 2000 are deductions.

Operations
In mathematics and computer science, an operation is an event that is carried out to satisfy a given task. Basic operations of a computer system are input, processing, output, storage, and control.
Basic Operators
An operator is a symbol that indicates an operation to be performed. We are familiar with operators in mathematics; operators used in computer programming are—in many ways—similar to mathematical operators.
Division Operator
We all learnt about division—and the division operator—in school. You probably know of both these symbols as representing division:
Modulus Operator
Modulus can be represented either as (mod or modulo) in computing operation. Modulus comes under arithmetic operations. Any number or variable which produces absolute value is modulus functionality. Magnitude of any function is totally changed by modulo operator as it changes even negative value to positive.
Operators
In the realm of programming, operators refer to the symbols that perform some function. They are tasked with instructing the compiler on the type of action that needs to be performed on the values passed as operands. Operators can be used in mathematical formulas and equations. In programming languages like Python, C, and Java, a variety of operators are defined.
