demonstrations.wolfram.com The Wolfram Demonstrations Project contains thousands of free interactive visualizations, with new entries added daily. The Euler phi (?) function (also called the totient function) is important in number theory; ?(n) is the number of positive integers less than or equal to n that have no factor in common with n. For example, TagBox[RowBox[{RowBox[{?, (, 5, )}], =, 4}], … Contributed by: Robert Baillie

In both these problems, the operation is multiplication.
1) In the group of units of Z/17Z find the inverses of [ 5], [8] and [10].
2) What elements do you have to REMOVE from Z/12Z to get a group?
