Positive and negative signs are unlike one another.
-2.5 and +3.5 are two numbers with unlike signs: one negative and one positive.
One rule is that the product of two integers with unlike signs will have a minus sign for the product.
negative
Subtract and the Keep the sign of the one that has more
what's 8+15=
To add two integers with unlike signs: -- Find the difference between their sizes, ignoring their signs. -- Give the difference the sign of the integer with the larger size.
Depends on how large each integer is. +1-2 or +2-1. Different signs depending on the size of the integers.
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.
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..
If the two signs are the same it is positive but if they are both different itis negative
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.
(-4)-(-9)=5
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)
