# Python as a calculator

Python is perfectly suited to do basic calculations. Apart from addition, subtraction, multiplication and division, there is also support for more advanced operations such as:

- Exponentiation:
`**`

. This operator raises the number to its left to the power of the number to its right. For example`4**2`

will give`16`

. - Modulo:
`%`

. This operator returns the remainder of the division of the number to the left by the number on its right. For example`18 % 7`

equals`4`

.

The code in the script gives some examples.

Instructions

**100 XP**

Suppose you have $100, which you can invest with a 10% return each year. After one year, it's \(100 \times 1.1 = 110\) dollars, and after two years it's \(100 \times 1.1 \times 1.1 = 121\). Add code to calculate how much money you end up with after 7 years, and print the result.
