最快都算係我啦 ! !

I = 1
X = 10

when I is written in front of something, it means using that something minus 1

so IX = 10 - 1 = 9

LXX

羅馬數字IX=9

羅馬數字IX是=9

咁易都唔識

係 9
I am sure

羅馬數字只有1(I),5(V),10(X),100(C),1000(M),而無2,3,4,6.7,8,9;所以看法是一條算式,I是1,X代表10,放在大數的右邊是相加,放在大數左邊是相減!
所以答案是X(10)-I(1)=9

羅馬數字IX是=9

It is 9
