The sum of the Roman numerals: V+XL+XLV = XC (90)
Expressed in Roman numerals, V + XL = 5 + 40 = 45 = XLV.
XLV = 45 (XL = 40; V = 5)
To represent forty five in Roman numerals, you would write it as "XLV." The numeral "XL" represents 40, and "V" represents 5, making a total of forty-five.
The Roman Numerals XLV represent 45. This can be seen as it is: X (Ten) before L (50), Which equals 40, and plus V (5).
Separate XL into two parts (XL) and (VII). Work on them separately, but remember that you must add them again at the end. XL means X many before L, where X is 10 and L is 50. Therefore XL means 10 before 50, or 40. VII means V plus I plus I, where V is 5 and I is 1. Therefore VII means 5 plus 1 plus 1, or 7. So adding the two quantities together, 40 plus 7 is 47. XLVII is 47 in cardinal numbers.
