Adding a positive and negative number, the sum will always be negative.
Example:
10+-20=-10
If you add two negatives, they cancel each other out making it positive.

When adding a positive number to a negative number what is a good rule for determining the sign of the sum?
If the negative number is a bigger number, the answer will be negative. Conversely, if the positive number is bigger, the answer will be positive. -20+10= -10 (larger negative number) -10+20=10 (larger positive number)
What is the rule for adding negative integers?
Adding negatives is exactly the same as taking away the positive number. Alternatively you can think of it as "imagine both the numbers are positive, add them together. This number is then negative. And you're done".
What is the rule in adding positive integers?
Adding IntegersTo add integers, one must consider the following two rules to be a successful.If you want to think of it on the number line you start from 0 and when you add a positive number you go that much to the right, and when you add a negative number you go that much to the left. When adding two positive integers, just add like normal. When adding one positive integer, and one negative integer, it is like subtracting a positive number from a positive number. When adding two negative integers, it is like subtracting a positive number from a negative number.
What is the rule when adding a negative and a positive?
Whichever number is higher you subtract the other one from it, and keep the sign of the higher number
What is the rule in adding integers with unlike sign?
it depends to the value of the number,when the greater value caries the positive sign,your answer must be positive,when it carries the negative sign,your answer is negative.

What are is the rule for subtracting fractions with negative signs?
the same as adding whole numbers. two negatives = negative. two positives = positive, and a negative and positive depends on the absolute value of the greater number.
Why is that negative number multiplied by a positive number a negative number?
Because that is the rule. negative * negative=positve positive *negative=negative and vice versa

How do you explain adding and subtracting negative numbers?
Adding a negative number is equivalent to subtracting a positive number. For example, adding -3 is the same as subtracting 3. Subtracting a negative number is equivalent to adding a positive number. For example, subtracting -3 is the same as adding 3. The rule to remember is that when you have a negative sign in front of a number, it actually changes its sign.
How do you subtract a positive by a negative?
Subtracting a positive number from a negative number is the same as adding two negative numbers, which is like adding two positive numbers except you're going to the left from zero on the number line instead of to the right. The rule is to add the absolute values (the numbers without the signs) of the two numbers and keep the negative sign. For example, -3 - 5 = (-3) + (-5) = -1 * (3 + 5) = -8.
What are the rule for dividing negative numbers?
The rules for dividing negative numbers is the same as multiplying them. A negative number multiplied/divided by a negative number is positive and a negative number multiplied/divided by a positive number is negative.
What is the rule for adding 2 negative integers?
The rule is if a number is positive you add them. EX: 4+4=8 But if the numbers are both negative... you forget the plus sign and just put the numbers together and use whatever sign they have. EX: -4-4= -8 you see? you are adding them put if they are negative, they go down the number line. not up. Just picture a number line, if you add a negative number to an already negative number, wouldn't the number go to the left? The answer is yes. Yes it would. :)
