Arithmetic operations
It’s possible to do mathematical operations with variables in Python. We have already seen that it’s possible to add them with
+ and multiply them with *. The full list of possible operations is:Operation | Description | With variables | Example with numbers |
+ | Addition | a + b | 10 + 7 ⇒ 17 |
- | Subtraction | a - b | 10 - 7 ⇒ 3 |
* | Multiplication | a * b | 10 * 7 ⇒ 70 |
/ | Division | a / b | 10 / 7 ⇒ 1.4285714285714286 |
// | Floor division | a // b | 10 // 7 ⇒ 1 |
% | Modulus (remainder after division) | a % b | 10 % 7 ⇒ 3 |
** | Exponent | a**b | 10**7 ⇒ 10000000 |
Challenge

x and print x - 1, x, and x + 1 in the output.Input | Output |
