Answer:


\huge\boxed{\text{+}}

Explanation:

To make this statement true, we want to make it so that when -20 is "something'd" to 18, we get -2.

Let's try all the common operators first - add, subtract, multiply, divide.

Let's try add.

If we put a plus sign there:


18 + (-20) = -2

Adding a negative is the same as subtracting a positive.


18-20=-2

This is true! 18 - 20 is indeed -2. This means + is the right operator.

For fun, let me briefly go over what happens with all the other operators.

Subtract:


18 - (-20) = -2\\\\18+20=-2\\\\28 \\eq -2

Multiply:


18 \cdot (-20) = -2\\\\-360 \\eq -2

Divide:


18 / (-20) = -2\\\\-0.9 \\eq -2

Hope this helped!
