1. XVIII+XXII=35
2.VI+XIX=25
3.M-CC=900
4.LXXXIV-XLII=44
5.VI x XI=66
6.X x V x I=50
7.C/XX=5
8.XC/VI=30
1, 3, and 8 are wrong.

1 is 40
3 is 800
8 is 15
Now they are all right. :-)
1.
XVIII = 18
XXII = 22
XVIII + XXII = 40 = XL
2.
VI = 6
XIX = 19
VI +XIX = 6 + 9 = 25 = XXV
3.
M = 1000
CC = 200
M - CC = 1000 - 200 = 800 = DCCC
4.
LXXXIV = 84
XLII = 42
LXXXIV - XLII = 84 - 42 = 42 = XLII
5.
VI = 6
XI = 11
VI x XI = 6 * 11 = 66 = LXVI
6.
X = 10
V = 5
I = 1
X x V x I = 10 * 5 * 1 = 50 = L
7.
C = 100
XX = 20
C / XX = 100 / 20 = 5 = V
8.
XC = 90
VI = 6
XC / VI = 90 / 6 = 15 = XV
Sure! Let's break down each equation one by one and explain how to get the answer.
1. XVIII + XXII = 35
To solve this equation, you need to convert the Roman numerals to their corresponding decimal values.
XVIII represents 18 and XXII represents 22.
So, 18 + 22 equals 40, not 35. The given information is incorrect.
2. VI + XIX = 25
Again, convert the Roman numerals to decimal values.
VI represents 6 and XIX represents 19.
So, 6 + 19 equals 25.
3. M - CC = 900
In this equation, M represents 1000 and CC represents 200.
So, 1000 - 200 equals 800, not 900. The given information is incorrect.
4. LXXXIV - XLII = 44
Convert the Roman numerals to decimal values.
LXXXIV represents 84 and XLII represents 42.
So, 84 - 42 equals 42, not 44. The given information is incorrect.
5. VI x XI = 66
Convert the Roman numerals to decimal values.
VI represents 6 and XI represents 11.
So, 6 x 11 equals 66.
6. X x V x I = 50
Convert the Roman numerals to decimal values.
X represents 10, V represents 5, and I represents 1.
So, 10 x 5 x 1 equals 50.
7. C / XX = 5
Convert the Roman numerals to decimal values.
C represents 100 and XX represents 20.
So, 100 divided by 20 equals 5.
8. XC / VI = 30
Convert the Roman numerals to decimal values.
XC represents 90 and VI represents 6.
So, 90 divided by 6 equals 15, not 30. The given information is incorrect.
Please note that some of the given information in the questions is incorrect or does not align with the expected results.
