Q: Rules in subtracting like and unlike signs?

Write your answer...

54453

to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..

They become positive integers for instance - - 2 = 2

Like signs: + and + , - and - Unlike signs: + and - , - and +

numbers with Like signs : result Plusnumbers with Unlike signs : result Minus

What is the definition of Adding and Subtracting Like Fractions

Like signs give a positive answer. Unlike signs give a negative answer.

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)

A negative number divided by a postive number equals negative number . Remember the rules of division of integers : Unlike signs = Negative Like signs = Positive .

When comparing two numbers-- Like signs means that both numbers are negative or both numbers are positive. Unlike signs means that one number is positive and one number is negative.

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

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.

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

The fractions are re-scaled so that the denominators are the same and then the numerators are subtracted as required by the signs.

because its just one of the rules of math :)

No, like signs multiply to positive, unlike to negative.

unlike charges attract each other and like charges repel each other. :)

Multiply each term of the binomial by the monomial. Be particularly careful with signs: (+ times +) or (- times -) equals plus or Like signs = + (+ times -) or (- times +) equals minus or Unlike signs = -

Adding and subtracting polynomials is simply the adding and subtracting of their like terms.

With both positive it's positive, with both negative it's negative.

because you subtract the 2 numerators and then 2 denominators right across just like that :)

Yes. A negative subtracted by a negative is a positive. Just remember that two like signs become a positive sign, and two unlike signs become a negative sign.

its like subtracting. so 26-5=21, -26+5=-21 it seems like your subtracting

Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"

++ = + +- = - Like signs always give me plus. Unlike signs always give me minus when I multiply! My maths teacher made us learn that! :D
