Room flutter is basically echo. Parallel surfaces of the room cause sound to bounce back and forth quickly causing the echo to quickly echo creating a flutter or slap back sound. This is usually NOT a desireable trait for a room especially if you're using the room for any kind of audio work (recording, mixing, rehearsing etc). I say usually because there are instances where you DO want a room to flutter, as when implementing an echo chamber. Remedies for this phenomina can be as simple as adding a carpet or soft furnature to full blown acoustic treatments (see auralex.com for more info on that)

If you subtract a negative integer it makes it positive.
