The distance of negative 3 to 0 is just 3 units and the distance from 0 to

positive 5 is 5 units. Remember, when we want the distance from 0, we want the

absolute value of a number. Absolute value is always positive. If you got that

right, great work. You really remember your stuff from Unit 1. If you're a

little bit fuzzy, that's okay. You can always look back at content to review

what you've learned. As you progress through this course, you'll often see

material that we've already covered. Math tends to build upon itself and it's no

different from Algebra. Be sure to go back to previous content if you're ever

unsure. Reviewing can always help you out.
