ok.. so U(10) = {1,3,7,9} under multiplication mod 10 and Z_12 = {0,1,2,3,4,5,6,7,8,9,10,11} under addition mod 12

Homework Statement Compute the direct sum Z_12 (+) U(10) Z_24 is the group Z under addition modulo 12 U(10) is the group Z under multiplication modulo 10 The Attempt at a Solution I have computed direct sums of Z_n groups before: For example: Z_2 (+) Z_3 =...
