Understanding arithmetic operators through repl in python

sure! understanding arithmetic operators in python is fundamental to performing basic calculations. let's go through the common arithmetic operators in python, using the repl (read-eval-print loop) environment to illustrate their usage.

### arithmetic operators in python

1. **addition (`+`)**: adds two operands.
2. **subtraction (`-`)**: subtracts the second operand from the first.
3. **multiplication (`*`)**: multiplies two operands.
4. **division (`/`)**: divides the numerator by the denominator (returns a float).
5. **floor division (`//`)**: divides and returns the largest whole number (integer value).
6. **modulus (`%`)**: returns the remainder of the division.
7. **exponentiation (`**`)**: raises the first operand to the power of the second.

### starting the repl

to start the python repl, open your terminal (or command prompt) and type `python` or `python3`, then hit `enter`. you will see the python prompt (``), indicating that you can start entering python commands.

### examples

#### 1. addition

#### 2. subtraction

#### 3. multiplication

#### 4. division

#### 5. floor division

#### 6. modulus

#### 7. exponentiation

### combining operators

you can combine multiple operators in a single expression. python follows the order of operations (pemdas/bodmas) to evaluate expressions:

### using variables

you can store values in variables and use them with arithmetic operators:

### example of complete code snippet

here’s a complete code snippet that you could enter into the repl to see how all the operators work together:

### running the code

### conclusion

arithmetic operators in python are straightforward to use and essential for any type of computation. understanding how they work and how to use them with variables will help you build more complex programs. practice u ...
