Compatible numbers are number that are easy to add together.
If I change 87 to 90 and 34 to 30 I have compatible numbers
90 + 30 = 120. I would probably just change the 87 to 90 since I could to 90 + 34 mentally and get 124 which is closer to the exact answer.
222 + 203 - becomes 220 +200 = 420
May I suggest that you can also balance the numbers: when you change 87 to 90 you added 3. To compensate, subtract 3 from 34 and get 31. 90+31= 121, the exact answer.
222 becomes 200 so you lowered it by two. To compensate add 2 to 203. Now you have 220+205= 425 which again, is the exact answer. Use estimation is needed but what I just showed you works well to and give you the exact answer.
One more: 199 + 306 = 200 + 305 = 505 (exactly) Instead of 200 + 300 = 500 which is a close estimate using compatible numbers.

Answer:
A stem and leaf plot shouldn't be used because the numbers are more than two digits long. These numbers are more varied, so it isn't correct for a stem and leaf plot. The stem is usually the tens digit, and the leaf is the ones digit. When you have four digits, it would get infinite times more hard and complicated. Hope that helped!
