By: Jimmy Pan

---

• Create a method that takes 2 integers, and returns the sum of the absolute value of both integers.

System.out.println(absoluteAdd(-5, -7)); // 12
System.out.println(absoluteAdd(6, -2)); // 8
System.out.println(absoluteAdd(-3, 1)); // 4
System.out.println(absoluteAdd(9, 4)); // 13
