Does the order of the input (by the user) matter?

Does the order in which the numbers are input by the user matter? Let's say the user puts in a bottomNumber (the starting number) that is larger than the topNumber. So, for instance, the user types in 25 first, and then 10 after. Will this make a difference in the results? Or does the formula account for errors of this nature? How so?

Hi Raquel! Of course this matters! If you ask your users to input a number first from 1 to 5 and then input some other number from 5 to 10 and they input lets say 7 and 15...you would have different results than expected. That's why you must add some kind of validation to your code in order to check if your users did input the desired numbers. Even further you must use validation and so in order to prevent your code from malicious code from some evildoers!
