-// Below are the steps for how BMI is calculated
-
-// The BMI calculation divides an adult's weight in kilograms (kg) by their height in metres (m) squared.
-
-// For example, if you weigh 70kg (around 11 stone) and are 1.73m (around 5 feet 8 inches) tall, you work out your BMI by:
-
-// squaring your height: 1.73 x 1.73 = 2.99
-// dividing 70 by 2.99 = 23.41
-// Your result will be displayed to 1 decimal place, for example 23.4.
-
-// You will need to implement a function that calculates the BMI of someone based off their weight and height
-
-// Given someone's weight in kg and height in metres
-// Then when we call this function with the weight and height
-// It should return their Body Mass Index to 1 decimal place
-
-function calculateBMI(weight, height) {
-    // return the BMI of someone based off their weight and height
-}
-
 // 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
