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.
Same rules as adding whole numbers with different signs.
Then you are adding two rational numbers with different signs! No big deal!
Rules: Unlike SignsSubtract the absolute value of the number and copy the sign of the number with greater absolute value.
You could be adding numbers that have different signs. Just a guess.
-You must memorize -To add 2 integers with different signs, find the difference of their absolute value -To subtract an integer, add it's opposite
sometimes true (when the rational numbers are the same)
The answer also has the same sign.
If you mean integers, well if you have two integers of the same sign that you are adding, add and the sign stays the same. If you have different signs, subtract and keep the sign of the one that has more. Regular numbers you just add them.
if the signs are different then u put the larger sing down then u subtract if if the signs are the same then u put the same sign down then u add
Temporarily ignore the signs and multiply or divide as usualIf signs of the two numbers to be multiplied or divided, add + sign to your answer. If signs are different, add - ( minus) to your answer.+ signs are optional-- a number without a sign is assumed to be positive.
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 product or quotient of two numbers that have the same sign is positive. The product or quotient of two numbers with different signs is negative.
You add all the numbers with + signs and subtract all that have minus signs.
-- Temporarily ignore the signs. -- Add the numbers without their signs. -- Give the sum the same sign as the original two numbers have.
Adding two numbers with different signs means subtracting the two absolute integers (without sign) and vice versa.
If the two numbers have different signs, then the result will be negative. If the two numbers have the same signs, the result will be positive. This assumes all the numbers are non-zero.
numbers with Like signs : result Plusnumbers with Unlike signs : result Minus
If the signs are the same, add the absolute values and keep the sign. If the signs are different, subtract the lesser absolute value from the greater absolute value and keep the sign of the number with the greater absolute value.
The value of the quotient of two integers with different signs is the same as if the signs were the same. Because the numbers have different signs, the quotient is negative.
With both positive it's positive, with both negative it's 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.
same signs add and keep, opposite signs subtract take the sign of the larger number, and then you'll be exsact!!! Hope I helped!!! :)
If you're adding a positive amount, keep the + sign; if you're adding a negative amount, multiply the + and - signs to convert it into a subtraction. Example: 4 + (-5) = 4 (+*-) 5 = 4 - 5 = -1
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.
