title: stuck on error with practice round function code
body: <h1>Basic code using the round() function along with print and input</h1>
  <pre><code>fullName= input(&quot;Enter your first and last name: &quot;)    
  print(&quot;Hello, &quot; + fullName + &quot; nice to meet you&quot;)    
  Age= input(&quot;How old are you: &quot;)    
  print(&quot;Wow, you're actually &quot; + Age + &quot; years old!? &quot;)    
  print(&quot;I will now move onto grabbing information and round functions&quot;)    
  milesdrivenA= input(&quot;How many miles did you drive to point A? &quot;)    
  milesdrivenB= input(&quot;How many miles did you drive to point B? &quot;)    
  gallonsusedA= input(&quot;How many gallons did you use to point A? &quot;)    
  gallonsusedB= input(&quot;How many gallons did you use to point B? &quot;)    
  totalMiles= str(milesdrivenA + milesdrivenB)    
  totalGallons= str(gallonsusedA + gallonsusedB)    
  mpg= round(totalMiles / totalGallons, 2)
  </code></pre>
  <p>Error:</p>
  <blockquote>
  <pre><code>TypeError: unsupported operand type(s) for /: 'str' and 'str'
  </code></pre>
  </blockquote>
  <p>Excuse all the extra things such as &quot;wow you're this years old&quot; it's honestly for extra practice in a way ( the more code i write the more familiar i'll get with what i'm doing).</p>
  <p>Now on to my question in the above code, what am i doing wrong? Might be a pretty straight forward answer but i'm truly super beginner so i don't know what exactly what i'm missing. i've tried things such as changing <code>totalMiles = ^</code> what's above to  <code>totalMiles= str( int(milesdrivenA + milesdrivenB ))</code>. Thanks for the help in advance!</p>
