XXLII is not a Roman numeral as it does not conforms to the rules of writing numerals. If it were a numeral you might suppose that it would represent... (20 less than 50) + 2 which is of course 32 but the correct Roman numeral for 32 is XXXII
M = 1000, XL = 40 (10 less than 50) so MXL represents 1040.
The number for Roman numeral LXXV is 75.
1944 M = 1000 CM = 900 (100 less than 1000) XL = 40 (10 less than 50) IV = 4 (1 less than 5)
It is: 50-30 = XX = 20

2n - 20 = 50
XXXL is not a real Roman numeral L = 50 and X = 10. Putting a 'smaller' letter in front of a 'larger' one was a way to signify "less than" so that XL = 40.... 10 less than 50. But the Romans would not have put three consecutive Xs in front of an L. Doing that would tend to indicate 30 less than 50, but that equals 20 and 20 was always represented by XX. Only one lesser numeral was ever put in front of a larger one. X = 10 XX = 20 XXX = 30 XL = 40 L = 50 LX = 60 LXX = 70 LXXX = 80 XC = 90 C = 100
50 - 20 = 30 degrees 20 is (30) less than 50 and 50 is (30) more than 20 hence difference is 30.
M = 1000, XL = 40 (10 less than 50) so MXL represents 1040.

The number for Roman numeral LXXV is 75.
1944 M = 1000 CM = 900 (100 less than 1000) XL = 40 (10 less than 50) IV = 4 (1 less than 5)
The correct answer is 20.
100 + 50 + 20 + 9 = 179
It is: 50-30 = XX = 20
The prime numbers between 20 and 50 are: 23 29 31 37 41 43 47
