Homework Statement
Find the order of the element 5 + <3> in the quotient group II18/ <3>.
Homework Equations
II18 = {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18}
<3> = {3,6,9,12,15,18}
5 + <3> = {5,8,11,14,17,2}
order is the number of elements
The Attempt at a Solution
I am thinking this II18/ <3> equals {3,6,9,12,15,18} and I have to find the order of that plus 5.
So I got the order as 6.
