My code is:

```var minNumber = parseInt(prompt("Please give me a minimum number: "));
var maxNumber = parseInt(prompt("Please give me a maximum number: "));
randomNumber = parseInt(Math.random() * (maxNumber - minNumber) + minNumber);
document.write("Your number is: " + randomNumber);
``` Not quite, because the last number will never get generated.

For example let's say range is 5 to 10.

parseInt(Math.random() * (10 - 5) + 5), Math.random() * 5 will give you a range between 0.000... and 4.999..., add 5 and it will give you a range between 5.000... and 9.999..., parseInt() will then return a range of 5, 6, 7, 8, and 9, but never 10

This is why we do + 1 and round down.

Math.floor(Math.random() * (10 - 5 + 1) + 5), Math.random() * 6 will give you a range between 0.000... and 5.999..., add 5 and it will give you a range between 5.000... and 10.999..., Math.floor will round it down and return a range of 5, 6, 7, 8, 9, and 10

I believe "parseInt(Math.random() * (10 - 5 + 1) + 5)" will technically work but it's purpose is not to remove decimals. It's purpose is to convert a string into a number.
