Positive numbers, on your door. Negative in your freezer.

No. Distance is never negative, and total distance travelled doesn't decrease during a trip. The distance from A to B is the same as the distance from B to A. Displacement, on the other hand, can be negative, and can decrease during a trip. The displacement from A to B is the same magnitude, but opposite sign, as the displacement from B to A. An example would be if you went from your home to a friend's house 1 mile to the east. After you reach your friend's house, you have travelled a distance of 1 mile and your displacement from your starting position is 1 mile. When you come back home from your friends house, you travel a distance of 1 more mile. Your total distance travelled is now 2 miles, but your displacement from your starting location is zero (because you are back where you started.)
The shape of the tip of a pencil could be an example.

Well, a negative connotation of house might be 'shack', and a positive connotation can be 'mansion'.
yES AND No
In the United States, generally negative. Americans associate having house servants with slavery, which gives the practise a negative connotiation. In other cultures, it can be more positive, especially when the servant is not a house servant. "Well done, thou good and faithful servant" or "Civil Servant" do not have the negative connotation.
Your body maintains homeostasis through negative feedback. This somewhat like using a thermostat to maintain a narrow range of temperature in the house.
A neutron. Those with a negative charge are electrons, and those with a positive charge are protons.
I have a programable thermostat but do not know how to regulate it.
No, not the battery. But anything that has a diode, transistor or is in any other way dependent on polarity may be fried... including your alternator.
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again.
The common household process that is often compared to the way the endocrine system maintains homeostasis is a furnace thermostat on the wall of a house. In a house a thermostat is set at a specific temperature. When the temperature in the house falls below this designated temperature, the thermostat is triggered and signals the furnace to turn on and begin heating the house. Once the temperature of the house is above the designated temperature, the thermostat signals the furnace to turn off. This process is called negative feedback. The endocrine also works in a negative feedback system to maintain homeostasis. An example of negative feedback in the endocrine system is the regulation of calcium levels. Parathyroid glands release parathyroid hormone (PTH), which regulates the blood calcium levels. If there is a decrease in blood calcium the parathyroid glands will secrete more PTH. Then the PTH stimulates the release of calcium from the bones into the bloodstream. If blood calcium levels increase too much, the parathyroid glands will reduce their production of PTH and less calcium will be released from the bones.
have you changed the battery in the thermostat?
