Hello! The teacher calculates the random number on the Math's operation. Can we create another variable that stores the subtraction between the higher number and the lower number instead?? and then process the Math's operation by only using that new variable? Thank you

Yes, you can. Please see my code below as I create a newNumber variable to hold this value and use later in Math.floor().
// Collect input from a user
const inputLow = prompt('Please provide your lowest number');
const inputHigh = prompt('Please provide a number');
// Convert the input to a number
const lowNumber = parseInt(inputLow)
const highNumber = parseInt(inputHigh);
//Create a new variable to hold highNumber - lowNumber
const newNumber = highNumber - lowNumber
if (lowNumber && highNumber) {
// Use Math.random() and the user's number to generate a random number
const randomNumber = Math.floor( Math.random() * (newNumber + 1 ) ) + lowNumber;
// Create a message displaying the random number
console.log(`${randomNumber} is a random number between 1 and ${highNumber}.`);
} else {
console.log('You need to provide two numbers. Try again.');
}
You can even take lowNumber and move it up to the new variable. Please see the code below. Please let me know if you have any questions about the code below.
// Collect input from a user
const inputLow = prompt('Please provide your lowest number');
const inputHigh = prompt('Please provide a number');
// Convert the input to a number
const lowNumber = parseInt(inputLow)
const highNumber = parseInt(inputHigh);
//Create a new variable to hold highNumber - lowNumber
const newNumber = highNumber - lowNumber + lowNumber
if (lowNumber && highNumber) {
// Use Math.random() and the user's number to generate a random number
const randomNumber = Math.floor( Math.random() * (newNumber + 1 ) );
// Create a message displaying the random number
console.log(`${randomNumber} is a random number between 1 and ${highNumber}.`);
} else {
console.log('You need to provide two numbers. Try again.');
}

Amazing stuff! thank you so much :)
To be honest, your code below does make more sense to me and it shows it much clearer. Thank you again for your help I am getting really slow at understanding JS, and I appreciate your prompt response and examples :)
