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.

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.
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.

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).....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)"

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.
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
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.

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.
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
