1). Find the difference between them. Forget about plus and minus, just subtract the smaller one from the bigger one. 2). Write the difference, and give it the sign of whichever original number was bigger.

Why do 2 negatives equal a positive?

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.


How do you know if a number will be positive or negative when adding?

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.


Can you get a zero if you subtract a negative integer and a positive integer?

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


When do you know when the integers are positive and negative?

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.


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


When you add two integers how do you know if the answer is positive or negative?

-- 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 smallest division of an integer?

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.


Why does multiplying negative integers by negative integers result in positive integers?

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|.


What is a negative plus a negative minus a positive?

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.


How do you add a positive number to a negative number?

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


How do you add and subtract negative decimals?

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.
