title: Operator '&&' can't be applied to operands of type 'int' and 'bool'
body: <p>im trying to find out if a number that is entered is both divisible by 9 and 13, but it wont let me use the operator i need, i know the variable types are wrong but i dont know how to make it so that the variable types are accepted, im new to coding so can the answer be as basic as possible without taking the piss</p>
  
  <pre><code>public bool IsFizzBuzz(int input)
  {
      if ((input % 9) &amp;&amp; (input % 13) == 0)
      {
          return true;
      }
      else
      {
          return false;
      }
  }
  </code></pre>
