+// Predict and explain first...
+//  =============> write your prediction here
+// I predict that the code will output 'undefined' because the function calculateBMI 
+// does not return any value yet.
+
+// =============> write your explanation here
+// The function calculateBMI currently has no return statement, so it will return 'undefined'.
+// To fix this, we need to perform the BMI calculation: 
+// BMI = weight / (height * height)
+// Then, we round the result to one decimal place using toFixed(1).
+
+// Finally, correct the code to fix the problem
+//  =============> write your new code here

+function calculateBMI(weight, height) {
+  const bmi = weight / (height * height);
+  return bmi.toFixed(1);
+}
+
+// Example:
+console.log(`The BMI of someone who weighs 70kg and is 1.73m tall is ${calculateBMI(70, 1.73)}`);
+// Output: The BMI of someone who weighs 70kg and is 1.73m tall is 23.4
