-## Comparison with the Greater Than Operator
+## Comparison with the Greater Than Operator (>)
 
-`>` (Greater Than) is a logical operator that returns true case the value on the left is higher than the one on the right.
 
-## Basic Solution
+### Problem explanation:
+· _Add the `greater than` operator to the indicated lines so that the return statements make sense._
+
+#### Hint 1
+The greater than operator `(>)` compares both operands using type coercion (converting data types if necessary) and returns `true` if the first one is greater than the second one.

+## Spoiler alert!
+
+**Solution ahead!**
+
+## Basic code solution:
 
 ```javascript
 function testGreaterThan(val) {
-  if (val > 100) 
+  if (val > 100) {  // Change this line
     return "Over 100";
+  }
   
-  if (val > 10) 
+  if (val > 10) {  // Change this line
     return "Over 10";
+  }
 
-  return "10 or Under";
+  return "10 or under";
 }
+
+// Change this value to test
+testGreaterThan(10);
 ```
+### Code explanation
+The function first evaluates `if` the condition `(val > 100)` evaluates to `true` converting `val` to a number if necessary. If it does, it returns the statement between the curly braces ("Over 100"). If it doesn't, it checks if the next condition is `true` (returning "Over 10"). Otherwise the function will return "10 or under".
