`input()` reads data entered by the user. The result of `input()` is initially a string. `split()` separates one input line into individual values using spaces. `map()` applies the specified conversion to each input value. The `-` operator subtracts one number from another. The `*` operator multiplies numbers. The `/` operator performs regular division and may return a decimal number. `print()` displays the program result. Print only what the problem statement requires.

**Connection to this task.** The `/` operator performs true division and returns a floating-point value in Python. This matters for averages, percentages, and formulas whose result may be fractional. The expression `salary * (100 - tax) / 100` shows how this idea is applied to the task data.
