Potential difference. Like the plus and minus on batteries...

There is a plus and minus side on all batteries to indicate the polarity of the battery - positive (+), negative (-), this way one knows which part to match with the device. Plus on the battery has to match the plus on the device and same for the negative in other for the device to function.

On objects there is also a plus and minus sign to match with the ones on the battery. You place the end with the plus sign in to match the end with the plus sign on the object and the end with the minus sign to match the minus sign on the object. Hope this helps!
A minus plus a minus will give a sum with a minus also.
A cart that has batteries connected in series with one plus and one minus cables may have three 12V batteries connected with two jumpers, instead of twice as many 6V batteries with five jumpers.
Yes it does. A minus is the opposite of something, so the minus of a minus is a plus.

A plus times a plus is still a plus. Below is the way I remembered it: If there is not a minus sign, it is plus (positive). If there is 1 minus sign, it is minus (negative). If there are 2 minus signs, it is plus (positive).
