 // Try breaking down the expression and using documentation to explain what it means

+// num represents a random integer between the minimum and maximum values (inclusive).
+// The expression Math.random() generates a random decimal number between 0 (inclusive) and 1 (exclusive).
+// By multiplying this value by (maximum - minimum + 1), we scale it to the desired range.
+// The Math.floor() function then rounds this value down to the nearest whole number, ensuring we get an integer.
+// Finally, we add the minimum value to shift the range to start from the minimum instead of 0.
