1. 7
2. -3
3. 4
4. 23
5. -482
6. 7
When a number is in lines (|-3|), it means you must find it's inverse.
So, let's solve the problems you listed.
Here is how you solve: If you have a negative number, take the digits and make positive. If you have a positive number, take the digits and make it negative.
|-7| = 7
|3| = 3
|-4| = 4
|-23| = 23
|482| = -482
|-7| = 7
Hope this answer helped you!
