# How do you know which wire is positive and which wire is negative in the stereo of the car rear specifically?

Positive is normally red or white with a red stripe. Negative is usually green or on rare occasions black. A multimeter will verify this.

## Related Questions -6 Yes the answer would be -6. But in order to get that answer you must know this: positive divided by a positive = positive positive divided by a negative = a negative negative divided by a positive = a negative negative divided by a negative = positive (also note: it's the same formula for multiplying) No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.) Look for a + by the positive terminal and a - by the negative terminal, or red for positive, black for negative. Some batteries have the positive terminal protruding and the negative terminal flat. Or you can get a meter that will tell you which is which, I honestly don't know :D but heres something to help you "MULTIPLICATION: minus times minus is plus (negative x negative = positive).....minus times plus is minus (negative x positive = negative).....plus times plus is plus (positive x positive = positive) DIVISION: minus divi minus is plus (negative ÷ negative = positive)......minus divi plus is minus (negative ÷ positive = negative).....plus divi plus is plus (positive ÷ positive = positive)" opposites: if it is a negative, make it a positive. if it is a positive, make it a negative absolute value: take the number without any sign. if it is negative, make it positive. if it is positive, keep it as a positive, Numbers are positive unless they have a minus sign (-) in front of them, in which case they are negative. As for the sum of positive and negative numbers, just add them up and find out. Add the positive, subtract the negative. It's very logical. Negative. There are VERY few positive feedback mechanisms in the body- the only one i know about is birth. Think of negative feedback and positive as a line. The sum of two positive numbers is positive. The sum of two negative numbers is negative. The sum of a positive and negative number will depend on which number has a greater absolute value. 5 + (-4) = 1 5 + (-9) = -4 negative numbers are numbers less than zero. negative numbers have a negative sign in front of them EX: -9 negative nine positive numbers are anything more than zero. EX: 9 positive nine You know when the slope of a line is negative when m in the slope-intercept form equation y=mx+b is negative. For example, y=-3x+2 has a negative slope since m (which is -3 in this case) is negative. This is the same when finding a positive slope, because if m is positive, then the slope is positive. I assume you're asking how can you tell which is positive and which is negative? The red cable is positive in the black cable is negative. But if they are not color-coded the positive battery post is slightly larger than the negative battery post. If you try to connect the negative cable to the positive post it would be a tight fit and if you connect the positive cable to the negative post it would be loose.
