In mathematics, the **symmetric difference** of two sets is the set of elements which are in either of the sets and not in their intersection. The symmetric difference of the sets *A* and *B* is commonly denoted by

or

or

For example, the symmetric difference of the sets and is . The symmetric difference of the set of all students and the set of all females consists of all male students together with all female non-students.

The power set of any set becomes an abelian group under the operation of symmetric difference, with the empty set as theneutral element of the group and every element in this group being its own inverse. The power set of any set becomes aBoolean ring with symmetric difference as the addition of the ring and intersection as the multiplication of the ring.

No there isn't, there are many different hole punchers that make holes at different spaces apart and different countries use different hole spacings.

Wikipedia has a chart of all the different hole punchers. http://en.wikipedia.org/wiki/Hole_punch#Chart.5B3.5D

parfumes smell different on different people because each individual had different natural smell and it alters the outcome. Changes in life, diet, taking medication will alter your natural smell as well and you may end up with a different smell even from the fragrance you have used before. Always try fragrance for at least 15 min on you skin before deciding if you like it or not.

Oftentimes a model number that is very similar simply denotes a color or packaging difference or the accessories packaged with the unit. Also, different stores will carry slightly different model numbers that are unique to their store so that they can avoid having to price match since the exact same model number won't be sold anywhere else..

Yes there are many difference between the old notebook RAM and new one.but it depends how much old is ur notebook.They can be same or different

As previous notebook contains different type of RAM but now a days they contain different one like DDR1 or DDR2.

So better you must go to h/w expert and ask him and confirm by showing that both are same or different.

It would take a week to list the differences. It's kind of like, the difference between your left shoe and your right glove.
