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 subtracting like and unlike sign?
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
What are the rules in adding real numbers?
Rules: Unlike SignsSubtract the absolute value of the number and copy the sign of the number with greater absolute value.
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 are the rules of addition?
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.
What are the rules in transposition of terms in equation?
A term may be moved from one side of an equation to the other if the sign of the term in changed from plus to minus or vice versa after the move. Note that this follows from the more basic rule that an equation is not changed by adding the same term to each side. Transposing a term and changing its sign is equivalent to adding the positive/negative counterpart of the term to be transposed to each side of the equation.
