Question

How is locating -1.5 on a number line the same as locating 1.5 on a number line? How is it different?

Answer 1

It’s the same in the sense that 1.5 and -1.5 are the same distance away from 0 - they have he same *absolute value*. It’s different in *where* you look. 1.5 is 1.5 to the *right* of 0, while -1.5 is 1.5 to the *left* of zero.
