15 becomes XV.

19 becomes XIX

25 becomes XXV

49 becomes IL

59 becomes LIX

===========

167 becomes CLXVII

Improved Answer:-

The way in which we write out Roman numerals today differs in the way that the Romans actually did themselves. For example today we would write out 19 as XIX but the Romans probably wrote it out as IXX because the Latin word for IXX is 'undeviginti' which means one from twenty.

From ancient manuscripts and monuments there are clues out there to show that the Romans would have probably wrote out the equivalent of 15, 19, 25, 49 and 59 simply as XV, IXX, XXV, IL and ILX respectively which makes addition straightforward as follows:-

XV+IXX = IXXXV (15+19 = 34)

IXXXV+XXV = ILX (34+25 = 59)

ILX+IL = IICX (59+49 = 108)

IICX+ILX = CLXVII (108+59 = 167)

Alternatively the Romans could have used an abacus counting device and calculated the above numerals in expanded format as:-

XV+XVIIII = XXXIIII (15+19 = 34)

XXXIIII+XXV = LVIIII (34+25 = 59)

LVIIII+XXXXVIIII = CVIII (59+49 = 108)

CVIII+LVIIII = CLXVII (108+59 = 167)
