Hi, I'm Jimmy Chang and we're here to discuss integers versus numbers. Now one thing you've got to think about is an integer is actually a number, it's just that integers are a subset of the numbers themselves. So let's talk about in layman's terms what integers are. Now integers are whole numbers both positive and negative so for example, 4 is a positive whole number, that makes it an integer. -12 is a negative whole number but that makes it an integer. As long as you have a positive or negative whole number you have an integer. Now, that also makes 0 an integer as well because even though 0 is neither positive nor negative it is at the end of the day, a whole number so what are non-integers? Well if you have -1.5 because that's not a whole number, it's only a number. It's not an integer. If you have, let's just say 5.1 or 22/7, neither of these numbers are whole numbers so therefore, neither of them are integers. They are both considered, however, numbers. If you have, let's just say the square root of 3, something funky like that or Pi, neither of these numbers are integers because they're not whole, they're just numbers. So I'm Jimmy Chang and that's a brief discussion on integer versus number.
