To arrange these numbers from east to greatest, you need to sort them in ascending order, starting from the smallest number (-66) and moving towards the largest number (49).

Here are the steps to arrange the numbers from east to greatest:

1. Start by identifying the smallest number in the given set, which is -66.
2. Next, find the next smallest number, which is -49. Since it is greater than -66, it comes after -66.
3. Then, locate the next smallest number, which is -44. Since it is greater than -49, it comes after -49.
4. Identify the next smallest number, which is -11. Since it is greater than -44, it comes after -44.
5. Finally, you have the largest number, which is 49. It comes after -11 since it is greater than -11.

Therefore, the arrangement of the given numbers from east to greatest would be: -66, -49, -44, -11, 49.
