Infixes di, tri, etc.

What is the significance of the "di" before the infix "en" in "4-Methylcyclohexa-2,5,-dienone"? When should one use "di," "tri", "tetra," etc. before an infix "en" "an" or "yn"?

Dien refers to there being two double bonds. The 2,5 should be placed in front of the group it is describing. So for example the diene is an unsaturated hydrocarbon containing two double bonds.
