0, Because you don't know how negative or how positive! 0, Because you don't know how negative or how positive!

Negative is the bottom half and positive is the top

It's a positive if you didn't like where you were. It's a negative if you don't know where you're going.

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

It the signs of the two numbers that you are multiplying or dividing is the same, then the answer is positive, otherwise the answer is negative. Remember though, that division by 0 is not defined.

-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)

It the two rational numbers have different signs, then the answer will be negative, otherwise it will be positive.

0, Because you don't know how negative or how positive! 0, Because you don't know how negative or how positive!

If I were you, I'd ask the same thing. When you're multiplying with different signs, the product will always change. Think of it as this... There is 1 negative. So it's a negative. But when there's 2 negatives, it's a positive. If you still don't get it, ask someone who might know. But this is what I learned. So, don't think of them as signs, but as a pattern. 1 Negative = negative 2 Negative = positive 3 Negative = negative 4 Negative = positive And so on...

Cations are always positive, anions are negative.

If you know that the product of 2 negative numbers is positive, then the product of 4 negative numbers has to be positive. The product of the first two negative numbers is positive and the next two negative numbers is positive. Multiplying the product of the first two numbers (positive number) and the product of the last two numbers (also positive), is a positive number times a positive number which is positive. Let a, b, c and d be negative numbers: (a*b*c*d) = (a*b)*(c*d) (-ve*-ve*-ve*-ve)=(-ve*-ve)*(-ve*-ve)= (+ve)*(+ve) = (+ve)

Any negative integer can be factored to -1 times its positive value. Because negative one times itself is positive one, when multiplied by each other they cancel out. So if you're multiplying a negative integer A by a negative integer B. Replace A and B with -1*|A| and -1*|B| (You can do this because you know A and B are negative), and use the distributive property to rearrange them. Now you can see the -1*-1 term and equate it to 1, leaving only the |A| and |B| behind. Because two positive numbers multiplied together are always positive, the result will always be positive. Represented algebraically, as long as A and B are negative integers, the following is true: AB = -1|A|*-1|B| = -1*-1|AB| = |AB|.

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.)

A negative. You really should know that.

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,
