Not sure if you want just a positive and a negative integer, added or more info.

2 positive integers a & b (easiest)

a + b the result is positive.

2 negative integers a & b

Add the magnitude of a and magnitude of b, the result is negative.

Example -2 + -5 = -(2+5) = -(7) = -7

a is positive, b is negative, take the difference of the magnitudes, then

if |a| (magnitude of a) greater than |b| (magnitude of b), the result is positive.

if |a| (magnitude of a) less than |b| (magnitude of b), the result is negative.

Example: 2 + -5 (the difference of magnitudes is 5-2 = 3

The negative number has a bigger magnitude, so the answer is negative: -3

-2 + 5

The difference is still 3, but the positive number has bigger magnitude,

so the result is positive: +3

Why does a negative number multiplied by a postive number equal a negative number?

That is part of the basic rules of Math: A: Multiply a Negative and a Negative will result in a Postive. B. Multiply a Negative and a Postive will result in a Negative. BTW, unlike English grammar, rules of Math are true at all times.

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 are the rules for adding and subtracting integers?

when you add two positive integers the answer is always positive when you add two negative integers the answer is positive when you add one negative and on positive integer, the answer is negative subtracting two negative numbers gets a negative answer subtracting two positive numbers- the answer depends subtracting a negative and positive number- the answer depends, the positive number would have to be bigger than the negative to achieve a negative number, and if the positive number is less, than the answer is still negative


What are the rules in adding subtracting multiplying and dividing integers?

Adding integers, if they have the same sign, add their absolute values and keep the same sign. Subtracting, change the sign of the 2nd number and the add using rules of addition. Multiplying and dividing, Divide the absolute values, if the signs are the same the answer is positive, if the signs are different the answer is negative.

The answer also has the same sign.


Rules for adding integers?

When you add: a negative and a negative: you get a negative a positive and a positive: you get a positive a positive and a negative or a negative and a positive: Subtract the addend with the smaller value from the greater one. If the greater one is positive, your answer will be positive. If the greater addend is negative, your answer will be negative.


What is the rules for multiplication integers?

When multiplying integers, multiplying by the same sign will always produce a positive integer. Such as a negative times a negative equals a positive. If the signs are different then the product will be a negative.


What are the rules for adding integers?

Positive + Positive = Positive Negative + Negative = Negative If it's a negative + a positive, it depends on the numbers. For example: -2 + 1 = -1 -107 + 213 = 106


What are the rules in adding integers with unlike signs?

For each pair of such integers, find the difference between the absolute values of the two integers and allocate the sign of the bigger number to it.


What is the rules for dividing integers?

If the signs (positive/negative) are the same, the answer is going to be positive. If the signs are different, the answer going to be negative.


How are adding subtracting decimals different from multiplying them?

They aren't. The rules are the same as those for adding/subtracting or multiplying integers. Just be careful of the decimal point's location.


What are the rules in adding integers with like and unlike signs?

To add integers with like signs you jut put the positive in front of the answer (you just add and put a positive sign in front of it)


What are rules in dividing integers?

negative times negative = positive positive times positive = positive negative times positive = negative positive times negative = negative


What are the rules for adding positive and negative numbers?

If you are adding a positive number, then this is the same as normal addition. For instance, 4 add positive 5 is 9. negative 1 add positive 8 is 7. If you are adding a negative number, then this is the same as subtracting that number. For instance 6 add negative 1 is 5. negative 7 add negative 2 is negative 9.

What are the rules for adding and subtracting positive and negative fractions with different denominators?

first must find Least Common Denominator http://www.loisterms.com/lois21.htm First of all, if you want to know about adding fractions, check out "How to Add Fractions". Be sure to follow the math examples carefully. To subtract fractions, follow the same steps as for adding, except subtract where you would add. Now about those positive and negative signs. The rules are the same whether you are working with integers or fractions. I will give you a method of learning the rules for the signs that has worked for many other students. Copy off this "Rules for Integers" chart and paste it on a large index card. Put the card in your math book or folder and refer to it often while you are doing your homework. If you keep using the card, you will get better with the signs.

How are multiplying integers and dividing integers same?

following multiplication integer rules and division rules, you should get: "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)" a division problem is a multiplication problem in disguise
