Operators help you perform actions on values.
  
  ## Arithmetic operators
  
  ```php
  $a = 10;
  $b = 3;
  
  echo $a + $b; // 13
  echo $a - $b; // 7
  echo $a * $b; // 30
  echo $a / $b; // 3.33
  echo $a % $b; // 1
  ```
  
  ## Comparison operators
  
  ```php
  var_dump(5 == "5");  // true
  var_dump(5 === "5"); // false (type matters)
  ```
  
  ## Logical operators
  
  ```php
  if ($age > 18 && $isStudent) {
    echo "Adult student";
  }
  ```
  
  > Next: if, else, and decision making.

Use arithmetic, comparison, and logical operators to build conditions and logic.
