What's 2*80 in Hexa?
EDIT: shady looking link
The result is shown to be 1B. How did we get this value?
So, this looks like a case of carry in hexa addition, so how'd we do this calculation?
I'm asking this question because of this. Here' for j=8, Round Constant is 80. The formula to find next round constant is to multiply the current round constant with 2. So, it's 2*80 and should be 100. But it's not the case. So, I want to know how is it done?

Edited the links, they did not look like good places to go. If they are legit, please just post the search terms that will point to them. Or an image.
1B hex is 27 dec so that makes as no sense.
