What are the V in each resistor?
Is it 6v in the left one and -6v in the right one? My logic is that as a 12v source is made of a 6v side and -6v side, we could see the circuit as that.
Sorry my monkey english

The voltage drop across each is 6 volts. The polarity of your measurement is determined by how you measure it.
Since the ground symbol is placed between the two resistors, that is your common reference point where you would place your black lead.
The one on the left will read +6v, and the one on the right will read -6v.
This is not because of what you said about a "-6 side and a +6 side".
There is 12 volts divided across two components so the sum of their individual voltage drops must equal 12 volts (absolute value). Doesn't matter how you measure it... reverse the leads and it reads the opposite polarity. (one side is more positive than the other)

The polarity of the Voltage across each resistor in the circuit is fixed and does not just depend on how you measure it.
What ever Voltage polarity it takes across each resistor to make the sum of the Voltage drops around the complete circuit equal to zero is the one and only Voltage polarity the resistors can have. The polarity of the only Voltage source in the circuit is given which leaves only one possible polarity for the Voltage drops across the resistors.
In this circuit the top terminal of the resistor on the right is 6 Volts more negative than it`s bottom terminal. The bottom terminal of each resistor is at the same Voltage potential. The top terminal of the resistor on the left is 6 Volts more positive than it's bottom terminal. These Voltage amplitudes and Voltage polarities are determined by the Amplitude (12V) and polarity of the source Voltage and will not change unless the values of the resistors are changed. If you measure any Voltage amplitude or polarity across the two resistors different from the above then you have the Voltmeter connected incorrectly.

If a battery has no connection then the voltage from it to some ground reference is undefined. Any voltage must be stated with respect to some other point, which is not nessarily "ground". In this case, a midpoint inside the battery will be at the same voltage as ground. For something similar see:
