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.
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.
Positive plus positive is positive. Negative plus negative is negative. Positive plus negative is positive if the absolute value of the positive number is greater than the absolute value of the negative one. Positive plus negative is negative if the absolute value of the negative number is greater than the absolute value of the positive one.
(positive number) x (positive number) = positive number (positive number)/(positive number) = positive number (positive number) x ( negative number) = negative number (positive number)/( negative number) = negative number (negative number) x (negative number) = positive number (negative number)/(negative number) = positive number
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
With both positive it's positive, with both negative it's negative.
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.
multiplying and dividing- positive * positive= positive positive * negative=negative negative *negative=positive subtracting- -3-6=? 1. freeze first number- -3 2.reverse the sign to a addition- -3+ 3.Reverse the sign of the number- -3+-6= -9 adding- keep the sign of the larger number, then add/subtract
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
The rules for division are exactly the same as the rules for multiplication. * Division (or multiplication) of a positive number by a positive number = positive * Division of a positive number by a negative number = negative * Division of a negative number by a positive number = negative * Division of a negative number by a negative number = positive If you have trouble remembering any of these, just try out a sample division on any calculator - for instance, if you divide (-1) / (-1) you get +1.

Rules When Dividing Positive and Negative Numbers:Rule 1: A positive number divided by a negative number gives you a negative number.Rule 2: A negative Number divided by a negative number gives you a positive numberRule 3: A positive number divided by a positive number gives you a positive number.
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.
The rules of integers state:~ two negatives make a positive number~one negative and one positive makes a negative number~ two positives are simply positive numbers
Positive x Positive =Positive Positive x Negative= Negative Negative x Positive= Negative Negative x Negative =Positive
Numbers are justified as positive, which is usually written as just a number but can be written with a plus (+) sign in front of the number. (e.g. 15 or +15), or negative. Negative numbers are numbers in the negative integers, or below 0. They are written with a minus (-) sign in front of them. (e.g. -15) ---------------------------------------------------------------------------------- ..::To solve remember these rules::.. When multiplying: positive x negative = negative positive x positive = positive negative x negative = positive When dividing: positive / negative = negative positive / positive = positive negative / negative = positive When adding: In a positive + negative situation, if the negative number has a higher number than the positive (e.g. -25 + 10) then the number is negative, this is always true when adding a higher negative to a positive. If the positive has a higher number (e.g. 25 + -10) then it's just the opposite, it will be a positive number. -------------You can solve these very easily: 25 + -10 --> (25) + (-10) to keep it well organized and easier to work with,now just remember "Keep Change Change"... - keep 25 as it is, change "+" to a "-" and change the "-10" to a positive 10. As a result, you will have: 25 - 10. Now solve. Answer = 15 (positive). If for instance you have a negative + positive, the same rules apply (Keep Change Change) negative + negative = negative positive + positive = positive When subtracting: negative - positive (vice versa), use Keep Change Change as you did with adding positives and negatives. negative - negative, use Keep Change Change positive - positive, use Keep Change Change if the number you are subtracting is a higher number. (e.g. 10-15) If you need anymore help, try asking a more specific question again on Wikianswers, search for math websites on the web, or ask your teacher or college professor for help.
A negative number divided by a postive number equals negative number . Remember the rules of division of integers : Unlike signs = Negative Like signs = Positive .
If you are talking about the multiplication rules than they would be; a negative times a negative is a positive a negative times a positive is a negative
negative times negative = positive positive times positive = positive negative times positive = negative positive times negative = negative
Due to the sign rules for multiplication, if you multiply several negative numbers, you'll get a result that is alternately negative, positive, negative, positive, etc.
Adding a negative number is just the same as subtracting a positive number. So 3 plus (-4) is the same as 3 minus 4. The answer to 3 - 4 is the inverse of the answer to 4 - 3 So if 4-3=1 then 3-4=-1 Other useful rules: Taking away a minus number is the same as adding a plus number. Subtracting a plus number, or adding a minus number, is the same as taking away a positive number.
Subtracting a negative is the same as adding the equivalent positive. For example, subtracting minus 10 is the same as adding 10.
When subtracting negative numbers change the subtraction sign to a plus and change the second number (which would appear to be positive) to a negative. ex. -14 - 7=?/-14 + -7= -21 When adding negative numbers just add them as they appear. ex. -2 + -5= -7
positive X positive = positive positive X negative = negative negative X positive = negative negative X negative = positive
It is the same rules that apply for multiplying them:positive and negative are negativepositive and positive are positivenegitve and negative are positive
