To design a website to perform mathematical calculations in server side.
### Step 1: Clone the repository from GitHub
### Step 2: Create Django Admin project.
### Step 3: Create a New App.
### Step 4: Create python programs for views and urls.
### Step 5: Create a HTML file of forms.
### Step 6: Publish the website in the given URL.
