Electricity

in the circuit below find the volts at V4
4 is grounded
R1 is 15 volts
R2 is 12 volts
R3 is 10 volts
www.ibiblio.org/kuphaldt/electricCircuits/DC/00082.png

15v+12v+10v =37v
if V1=37v,
then v2=37v-15v = 22v,
then v3=37v-15v-12v = 10v
then v4= 37v-15-12v-10v =0v

At V4 the voltage is at 0v
is my answer correct???
