If the number is zero, then it is neither positive nor negative.For all other integers: If there is a minus sign, "-", before the integer, then it is negative. If there is a plus sign, "+", before the integer or no sign at all, then it is positive.

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

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

The same way you'd add any other negative numbers. Adding a negative is the same as subtracting, and subtracting a negative is the same as adding. (-2) + (-2) = (-4) (-2) - (-2) = 0 you are wrong if you add or subtract two negitives its always a positive dont you know your math. And the second problem you have is wrong to because when you subtract two negitives you change the sign of the secong number to positive and you change the subtraction sign to a addition sign.

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.

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)"

Short answer: Yes. Long answer: it depends on the order. If x is negative and y is positive, then x-y<0; y-x>0 (this second one is only correct if |y|<>|x|). And if |y|=|x| then y-x=0 (this is the one you're looking for, where x and y are equal, but y is positive and x is negative). Finally, if you know if |y|=|x| or |y|<>|x| then y-x>=0

On the number line if you subtract a positive you move left. If you add a positive you move right. If add a negative you move left. If you subtract a negative you move right. That is just how I learned it. I don't know a wordy explanation.

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.

-- If they both start out with the same sign (both negative or both positive), then do this: . . . . . add their two values . . . . . the answer has the same sign as the two original integers. -- If they start out with opposite signs (one negative and one positive), then do this: . . . . . forget about the signs . . . . . find their difference (subtract the smaller number from the larger one) . . . . . give it the sign of whichever original integer was the larger number.

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

an example is 11 + -18 first you subtract 11 from 18 and get -7 now since you know that 7 is your answer this is how you got it keep 11 and change the additon sign(+) to a subtraction sign(-) then change negative eighteen (-18) to positive eightteen(18) know subtract 11-18 and you get -7

we know that integer may be positive or negative and every integer may be prime number or not a prime number, but the common point of these two numbers is that is one factor is common, which is 1.basis of this the smallest division of an integer is 1.
