n = e + y and m = 4 + z from the table

So m + n = 4 + z + e + y = (e + z) + (4 + y) = 10 - 5 (from table) = 5

If you draw out the table and work through each one, took me under 2 mins to solve

+ X Y Z

4 1 -5 M - From this line we know that X = -3 and Y =-9

E 7 N 10 - From this line and using the above we know that e = 10
and N = 1 and Z = 0, hence M = 4

F 2 -4 5 - Can work this out to test logic

Hope this makes sense!

2 minutes huh? How long does it take to just look in the little square with the m and the n and add 10 and -5 together? Filling in the dot takes longer....
