It seems to me just as straightforward as taking 2 at a time. For example,
if you have four elements A,B,C,D, the ways of taking three at a time are

A*B*C
A*B*D
A*C*D
B*C*D

If you have five elements A,B,C,D,E, the ways of taking three at a time are

A*B*C
A*B*D
A*B*E
A*C*D
A*C*E
A*D*E
B*C*D
B*C*E
B*D*E
C*D*E

Where are you getting stuck?
