 // Line 1 is a variable declaration, creating the count variable with an initial value of 0
 // Describe what line 3 is doing, in particular focus on what = is doing
+
+// Answer
+// Line 3 is an assignment operation. The = operator assigns the value of the expression on its right
+// (count + 1) to the variable on its left (count). This effectively increments the value of count by 1.

@@ -7,3 +7,9 @@ const num = Math.floor(Math.random() * (maximum - minimum + 1)) + minimum;
 // Try breaking down the expression and using documentation to explain what it means
 // It will help to think about the order in which expressions are evaluated
 // Try logging the value of num and running the program several times to build an idea of what the program is doing
+// Answer
+// The expression generates a random integer between the minimum and maximum values (inclusive). 
+// Math.random() generates a random decimal number between 0 (inclusive) and 1 (exclusive). 
+// Multiplying this by (maximum - minimum + 1) scales it to the range of possible integers. 
+// Adding minimum shifts the range to start from the minimum value. 
+// Finally, Math.floor() rounds down to the nearest whole number, ensuring that num is an integer within the specified range.
