**Tell us what’s happening:**

I’m not passing the 42 42 42 42 test. My code is allowing this to go through, but it shouldn’t. I looked at some solutions and some people put **/^(\d+)\s\1\s\1$/** , but I don’t understand why they put a caret and a dollar sign on the expression. The caret sign means negation. Why would they negate the capture values? The dollar sign means a repetition at the end. Why is that there? Can someone explain why those symbols allow this to work? Thanks.

**Your code so far**

```
let repeatNum = "42 42 42";
let reRegex = /(\d+)\s\1\s\1/; // Change this line
let result = reRegex.test(repeatNum);
```
