1. If the positive number is larger in absolute value, subtract the absolute values of the numbers, and then put the positive sign in front of the answer.

2. If the negative number has larger absolute value, subtract the absolute values of the numbers and then put the negative sign in front of the answer.

3 . If they are the same, the sum is 0.

Example of 1: 10+(-5). We know that 10 is larger absolute value. S0 10-5=5 and put a + in front. The answer is +5 or just 5.

Example of 2. -10+5. The =10 has larger absolute value. 10-5=5. Now put a - sign so the answer is -5

Example of 3. is is -5+5. The numbers have the same absolute value so their sum is 0.

Remember the absolute value of x, denoted | x | is the distance of x from zero on the number line. So |-3|=3 and |5|=5 since =3 is 3 units from 0 on the number line and 5 is 5 units from 0 on the number

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.

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.


What is the rules in solving integers?

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


What is the rule in adding integers with unlike sign?

it depends to the value of the number,when the greater value caries the positive sign,your answer must be positive,when it carries the negative sign,your answer is negative.
