 # Python as a Calculator

We can use Python as a quick and handy calculator. We can perform all the basic four operations - addition, subtraction, multiplication, and division in Python.

Examples

• To add 4 and 2, use `+`

``````4 + 2
``````

It returns `6`

• To subtract 2 from 4, use `-`

``````4 - 2
``````

It returns `2`

• To multiply 4 and 2, use `*`

``````4 * 2
``````

It returns `8`

• To divide two integers 5 by 2, use `/` to get the complete value and `//` to get the integer value

``````5 // 2
``````

It returns `2`

``````5 / 2
``````

It returns `2.5`

• Every line of the code is called `expression`.

`4 + 2` is one expression and `4 - 2` is another expression.

Run above expressions in the Jupyter notebook on the right-hand side and make yourself comfortable with addition, subtraction, multiplication, and division in Python. Remember to execute the cell in the notebook, press `Shift + Enter`

INSTRUCTIONS

Peter is driving a car at a speed of 25 kilometers per hour. Calculate the distance covered by him in 4 hours

• The formula of distance is

``````distance = speed * time
``````
• Here speed is `25` and time is `4`

• Multiply 25 and 4 on the right-hand side and execute it
