Rules in addition and subtraction of algebraic expression?
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.
Is the sum of two integers positive negative or zero?
The sum of two positive integers is positive. The sum of two negative integers is negative. The sum of one positive integer and one negative integer has the same sign as the addend with the greater absolute value. If the absolute values of the two addends are equal, the sum is zero.
Negatives are never absolute values WHY?
The absolute value is the distance from 0 on the number line. -5 is 5 away from 0. You cannot have a negative distance, therefore you cannot have a negative absolute value. Absolute values are not ALWAYS positive because absolute values can be zero as well. Zero is not positive nor negative.
What measurement uses absolute values?
distance
What do you do when subtracting a positive and a negative?
If you subtract a negative from a positive, add both of their absolute values. If you subtract a positive from a negative, add both of their absolute values and multiply by negative one.
When adding integers with the same sign do you add their absolute values and write the common sign?
yes.
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 product of 3 integers with the same sign?
It is the product of their absolute values with the common sign.
What is the connection between absolute value and integers?
None. Integers can be negative, absolute values cannot. Absiolute values can be rational or irrational fractions, integers cannot.
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.
What is the rule for adding integers and rational numbers with the same sign?
The value of the answer is the sum of the absolute values of the numbers and the sign of the answer is the same as that of the two numbers.
What are the two rules for adding integers?
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.
Do only integers have absolute value?
No. Absolute value applies to the set of real numbers.
Rules for adding and subtracting integers?
ADDING: same sign, add and keep that sign. opposite sides, subtract their absolute values and use the sign of the number with the larger absolute value SUBRTRACTING: change the sign of the subtrahend (2nd number) then ADD using rules above.
How is absoulute value different from positive and negative integers?
The absolute value is always non-negative. So, the absolute values of zero and positive integers are the same as the numbers. However, the absolute values of negative integers are their additive inverses or additive opposites (or positive equivalents).Thus, for example, abs(-3) = +3
Can you use the same rules to add integers that have really big absolute values?
Yes, you can.
What do you get when you add a positive and negative number?
First, subtract the absolute values of the integers, then use the greater absolute value's sign.
