The difference between compatible numbers and estimation is that in estimation you round to the nearest ten or hundred most of the time. Compatible numbers are numbers that are easy to compute mentally. Some examples of compatible numbers when doing division are 400 and 10, 36 and 6, 2400 and 12, and 64 and 8 2400 and 12 are compatible because when doing this division (2400/12), we can quickly divide 24 by 12 to get 2 and put two zeros at the end to get 200 Some examples of compatible numbers when doing multiplication are 200 and 40, 1100 and 40, 25 and 4. 1100 and 40 are compatible because we can quickly do this multiplication by multipling 11 and 4 to get 44 and add three zeros at the end to get 44000 Hope this helps!
o that's easy....it just means to do the math in your head instead of working it out on paper

It depends on your computational skills.

Your brain, of course.
No, but if you practice you can learn to do it and it gets easier. Start of by learning (by rote) your times tables and when adding up do so in 10s.

Break it up into two separate problems. First 4X25=100, which is easy enough. Then 27X100=2700.
