TS is right.

On one hand, the second post is right too. Bcos it calculates the average price nights. Say Saturday night is much more expensive than Sunday night. So, the Saturday's night price will push up the average price.

But I have also checked on certain hotels where if u book individual nights, it is cheaper compared to booking several nights at once.

So, u have to check carefully before booking.

Provided it's the same room type.

Better if u send an email to the hotel to remind them that you have booked individual nights and tell them to arrange for u to stay in the same room consecutively.

Or else the staff may not know about it and might arrange for u to stay in different rooms on different nights and as a result, u have to check out and check in again.
