Find the sum XLI + XII
53
XL = 50 - 10 = 40
(∵ If a symbol of smaller value is written to the left of a symbol of greater value, then its value is subtracted from the symbol of greater value.)
XLI = 40 + 1 = 41
(∵ If a symbol of smaller value is written to the right of a symbol of greater value, then its value gets added to the symbol of greater value.)
XII = 12
∴ XLI + XII = 41 + 12 = 53
