Which three integers lie between negative two and it’s opposite on a number line?

Let’s start this problem by sketching a number line. Here’s our number line, and the point in the middle will be where a zero is. The first number we were given is negative two. Let’s graph negative two. We’ll put negative two, two spaces to the left of zero. Now we need the opposite of negative two. The opposite of negative two would be the value that if we added it to negative two would give us a result of zero, and that value is positive two. Negative two plus two equal zero. The next value we’ll graph on our line is the opposite of negative two, which is two.

And now I’m looking for three integers that lie between negative two and positive two. What integers are there? Between negative two and zero, there’s an integer, negative one. Between zero and two, there’s a missing integer of one.

The three integers that lie between negative two and two are negative one, zero, and one.
