• A negative number is any number that is worth less than 0.

-4 is a negative number because it is worth less than 0. -4 would be found to the left of 0 on the number line.

• It is so strange how "0" doesn't have an opposite like -0
(15 votes)
• That's because if there was a 0 in the whole numbers world and a 0 in the decimal world, it would make sense, or at least for me it wouldn't.

• All videos have been great so far. But the videos about absolute numbers have not helped me much to pass the tests. I feel like I am back at school again when teachers stand over my head and wonder why I don't get it. All the other videos have been so good. :( I simply cannot get the info I need from the related videos

Is it just me? Or does anyone else share my experience with these particular videos?
