    Imagine you're in a hole. we can think of negative numbers as how many feet you're down a hole |dw:1444556280721:dw|

    thanks haha! no, if you're "exactly" at 7 feet down that hole, you cannot say that you're less than 7 feet down a hole. for example, if you're exactly 7 feet tall, is it correct to say that you're more than 7 feet tall ?
