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.

What is the quotient of positive and negative integers?

How do you subtract a negative and a positive?

It depends on the way you want to perform the subtraction. Reading the content of the question, I'll assume you want to subtract a positive number from a negative number.Actually, this can be done quite easily. Remember when you were taught that adding two negative numbers results in an even lesser negative number? You can do the same with a negative and a positive.For example: -5 + -5 = -10, when adding two negativenumbers.But with -5 - 5, you can simply count to the left: -5, -6, -7, -8, -9, -10.Or, you can convert this to a negative number and add the numbers together, arriving at the same result.Hope this helps, let me know if you have any more issues regarding negative numbers.

How do you know when the sum of a positive integer will be negative?

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

Does a positive plus a negtitve equal positive?

I think you're mixed up with the multiplication rules. But I know a much easier trick for multiplication rule. You count the number of negatives there are in the operation. If the number of negatives is an even number than the answer is positive. If there is an odd amount then the answer is negative. his only works for multiplication and division. You won't know if the answer os a positive plus a negative is until you determine the numbers. For example: 4+(-2)=2 but 2+(-4)=-2 If the positive number is bigger than the negative number (not counting the negative sign) than yes, the answer is positive. If the negative is bigger than your answer is negative. That'll be...1 trust point now.

Why does a negative divided by a negative give a positive result?

It's saying subtract a negative number, so take away from something that negative is adding something positive. Think about it like this, If you have a number 5, and someone says to you take away from 5 negative 2, you'd have 7. If what you subtract from something is negative, you gain. I know it may not make sense, but think about it for a bit and I'm sure you'll get it, if not, just remember to do it when you're doing your work.

6 divided by negative 1?

-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)

Why is the product of a positive integer and a negative integer a negative integer?

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) 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) divi plus is plus (positive ÷ positive = positive)"

What combination of signed numbers always leads to a positive number?

If I understand the question correctly, the sum of two positive numbers will *always* yield a positive number. The product of two positive or two negative numbers will always yield a positive number. The division of two positive or two negative numbers will always yield a positive number. There are more examples along this line. I am not sure if this is what you wanted to know.

Why does a negative number times a negative number have a positive product?

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...

How will you know the exponent of scientific notation is negative or positive?

The smaller number at the top right of the ten may or may not have a negative sign in front of it: like 6.2 x 102 or 6.2 x 10-2. If the little number is positive, the decimal in the first number will move to the right. If the exponent is negative, the decimal in the first number will move to the left.

Why does the product of 4 negative numbers equal a positive?

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)
