title: Pygame Basic calculator
body: <p>I am trying to make a basic calculator but the problem I am having is how do I output the text? How do I make it so when I click plus it allows me to add or if I click divide it allows me to divide and shows the output on the yellow part on my screen</p>

  <p>This is what I have right now. You could run it; there is nothing special. <em><strong>My question is how could I make the calculator make it so when I click plus and then go and add up numbers it allows me to add or when I click divide it allows me to divide my numbers and show the outputs on the screen?</strong></em></p>
