We use them to:
-
Add numbers
-
Subtract numbers
-
Multiply numbers
-
Divide numbers
2. List of Arithmetic Operators
| Operator | Name | Example |
|---|---|---|
+ |
Addition | a + b |
- |
Subtraction | a - b |
* |
Multiplication | a * b |
/ |
Division | a / b |
% |
Modulus | a % b |
** |
Power | a ** b |
// |
Floor Division | a // b |
3. Addition (+)
Adds two numbers.
Example
Output:
4. Subtraction (-)
Subtracts one number from another.
Example
Output:
5. Multiplication (*)
Multiplies two numbers.
Example
Output:
6. Division (/)
Divides one number by another.
Result is always decimal (float).
Example
Output:
