1) CCXIX

C = 100
X = 10
I = 1

because there are 2 C's I added them together and I got 200
because there are 2 X's I added them together and got 20
because there is 1 I that equaled 1
So I added 200 + 20 + 1 = 221 which is my final answer

But according to the back of the book the answer is 219. Please help me determine how they got 219 for the answer or am I correct. Thank you

Answered by Writeacher
Bobpursley and your book are right.

I = 1
II = 2
III = 3
IV = 4
V = 5
VI = 6
VII = 7
VIII = 8
IX = 9
X = 10

Notice that 4 is made by putting I in front of V. 5-1=4

Notice that 9 is made by putting I in front of X. 10-1=9

Let us know if you have questions.

How does IX equal 9? I thought X represented 10 and I represented 1?
