Question

How many numbers are 10 units from 0 on the number line?

Answer 1

On a real number, the number 0 is at the middle of it. And from that point, you can go two ways, the negative direction or the positive direction. So, you can go 10 units to the left, which is the negative direction, or 10 units to the right, which is the positive direction.

So, there are 2 numbers that are 10 units away from 0.

Answer 2

It would be 10 to the right when you add from 0
