It is: XC = 100-10 = 90
It is: XC = 100-10 = 90
The Roman numeral XC represents the number 90
XC
In Roman numerals, 90 is represented as "XC". The letter X represents the value 10, and C represents the value 100. To represent 90, we subtract 10 from 100, which gives us XC.
The number 90 is represented by the Roman numeral XC
C stands for 100 and X stands for 10. In this case the number would be 90.
In the Roman numeric system, symbols are given value. When a smaller value symbol proceeds a higher value symbol, then the smaller value symbol is subtracted from the high value symbol. In this case XC is equal to 90 (X =10, C = 100. So XC equals 100 - 10 or 90). The symbols that hold numeric are I = 1, V = 5, X = 10, L = 50, C = 100, D = 500, M = 1,000.
The Roman numerals XC (100-10) or LXXXX (90) both have the same values of 90 in Arabic numerals (the numbering system that we use today).
xc = 100-10 = 90
It is: XC = 100-10 = 90
XC means 90. The C is a hundred, and the X is ten; when the smaller number is placed in front of the larger number, that is used to indicate subtraction, and 100 - 10 = 90.
21 in Roman numerals is XXI. 1 in Roman numerals is I. 90 in Roman numerals is XC. So, 21 1 90 would be XXI I XC in Roman numerals.
