(21 + 21 + 19 + 19)/4 = 20
2 goes into 19 9 times with 1 left over. it does not go into 19 equally though. divide 19 by 2.
mean = 19.833... median = 19.5 mode = 19
It means 19 multiplied by itself five times: 195 = 19 x 19 x 19 x 19 x 19 = 2,476,099
This math riddle relates to Roman Numerals where 19 is IXX, 1 is I, and 20 is XX. By removing I from IXX, you are left with XX.
