Find each of the numbers below.

Let's find each of the requested numbers:

1. The opposite of -2: The opposite of any number \( x \) is \( -x \). So, the opposite of -2 is \( -(-2) = 2 \).

2. The opposite of 0: The opposite of 0 is simply 0, since it is neither positive nor negative.

3. The opposite of the opposite of 7: The opposite of 7 is -7, and the opposite of -7 is 7. Thus, the opposite of the opposite of 7 is 7.

To summarize the answers:

1. The opposite of -2 is \( 2 \).
2. The opposite of 0 is \( 0 \).
3. The opposite of the opposite of 7 is \( 7 \).
