serious [3.7K]

Answer:

The answer is -5.

Step-by-step explanation:

Step 1: If you want to get the answer easier, you should use the number line way.

Step 2: If you don't know how to use a number line then go backwards from 18 until you have are done counting, for example;

17, 16, 15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1, 0, -1, -2, -3, -4,<em><u> -5.</u></em>

Since -5 ( negative five ) is the 23 ( twenty-third ) number you counted back from, you are done counting and now you have gotten your answer of -5!
