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)
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
They become positive integers for instance - - 2 = 2
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.
No- adding negative numbers is like adding positive numbesr , except the answer is negative.
The numbers can have a positive or negative sign.
positive + positive = positive negitive + negitive = positive negitive + positive = negitive
Like signs give a positive answer. Unlike signs give a negative answer.
Addition:1. look for like terms, combine like terms by adding their numerical coefficient. In adding the numerical coefficient, you have to consider the rules in adding integers.a. to add two numbers having like signs, add their absolute values and prefix their common sign, then bring down the literal coefficient.b. to add two numbers having unlike signs, find the difference of their absolute values and prefix to the difference sign of the number having a greater absolute value, then bring down the literal coefficient.Subtraction:1. multiply the subtrahend by -1 and proceed to adding algebraic expression.
I am not at all sure that there are any rules that apply to integers in isolation. Any rules that exist are in the context of binary operations like addition or multiplication of integers.
A negative number divided by a postive number equals negative number . Remember the rules of division of integers : Unlike signs = Negative Like signs = Positive .
It's pretty much the exact same. Subtracting is the same as adding a negative number. Foe example, five minus three is the same as five plus negative three.
No.For the sum of integers:-- two positives make a positive-- two negatives make a negative-- the sum of mixed signs is the sign of the one with the greater absolute valueFor the product of integers:-- like signs make a positive-- unlike signs make a negative
These mnemonic devices were developed by SHERWIN E. BALBUENA, mathematics teacher of Cabitan NHS, Mandaon, Masbate, Philippines", to teach his students with disabilities the rules in operating signed numbers. LA US means "Like signs Add, Unlike signs Subtract". This device lets the student remember the rule in adding signed numbers. LP UN means "Like signs Positive, Unlike signs Negative". This device lets the student recall the rules in finding the product and quotient of two signed numbers.
positive integers are like 2,3,4,etc... negative integers are like -2,-4,-9etc....
additionslike sign -just add and copy the sign of the integersunlike signsubtract the integers then copy the sign of the bigger integers.subtractionchange the sign of the subtrahend and proceed as in adding integers.multiplication and Divisionwith like signsthe product or quotient is positiveunlike signthe product or quotient is negativeby:jen Marie :)
Not really, because its just flipped over like 2-3 that because keep change change so 2+(-3)= -1
Procedure: 1. Divide the integers like you always do. 2. Follow these rules: (Note:+ is a positive integer, - is a negative integer and * is the multiplication symbol) a.+*+=+ b.+*-=- c.-*+=- d.-*-=+ Follow these rules and you will have your answer in no time.
Like signs: + and + , - and - Unlike signs: + and - , - and +
adding1. like sign, add their absalute value & copy the common sign.2. unlike signs. subtruct their absalute value & copy the sing of the bigger number.subtructing1. change the sign of the subrahend (if + change to - & if - change to +)2. then go back to the rules in addition.multiplying & dividing1. likes signs, simply perform the operation then the answer's sign would be (+) positive2. unlike signs, simply perform the operation then the answer's sign would be (-) negative
No. A negative plus a negative will always be negative. Adding negatives just makes them more negative, just like adding positives makes them more positive.If you're thinking of multiplication, then the answer is yes. Like signs result in positive values. Opposite signs result in negative values.
adding fractions is like adding a WHOLE lot of parts of numbers
