Firstly, you've used 'l' inappropriately. I assume you meant 'I' not 'l'.
Secondly, those are Roman numerals -- you really want to know what the Arabic equivalent of those numerals are.
x = 10
xxvii = 27
xi = 11
Just in case you really meant L not I:
xxvll is invalid (V cannot precede L and L cannot be repeated in succession)
xl = 40
XL is equivalent to 40 in Roman numerals, and X represents 10. Thus, XL plus X is 40 + 10, which equals 50. In Roman numerals, 50 is represented by the letter L.
If you mean as in Roman numerals then X = 10 and XL means -10+50 = 40
On converting between Arabic and Roman Numbers ,we get : XL IN ROMAN NUMERALS is written as : 40.
Their equivalents are: 40, 1 and 10 respectively
40. L is 50. Putting the X behind the L means you subtract the 10 from the 50, and you get 40.
XL is equivalent to 40 in Roman numerals, and X represents 10. Thus, XL plus X is 40 + 10, which equals 50. In Roman numerals, 50 is represented by the letter L.
If you mean as in Roman numerals then X = 10 and XL means -10+50 = 40
On converting between Arabic and Roman Numbers ,we get : XL IN ROMAN NUMERALS is written as : 40.
(xl)mdxxix (xl) = 40,000 m = 1,000 d = 500 x = 10
Their equivalents are: 40, 1 and 10 respectively
40. L is 50. Putting the X behind the L means you subtract the 10 from the 50, and you get 40.
Xl-l. X=10. L=50
It is: XXXX or XL which means 40 or (50-10)
XL (X = 10 and L = 50) 50 - 10 = 40
X=10 L=50 XL=40 XLI=41
In Roman numerals, M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, and I = 1. A single Roman numeral of lesser value placed before a Roman numeral of higher value means to subtract the lesser one. So, XL means 50 - 10 = 40.
In Roman numerals X = 10 and L = 50. The numeral XL (10 before 50) represents the number 40.
