I have a math test, coming up. It would be nice if someone could explain, adding and subtracting integers for me.

An integer is a whole number; a number that is not a fraction.

 

Adding is group two things together and subtracting is taking something away from something else.

 

2 + 4 = 6

 

9 + 10 = 21, I mean 19

 

21 - 10 = 11

 

x - x = 0

 

Hope this helps! Good luck on the test!

Here is a very old post that you may find very helpful.

 

The original question is a little different from yours so be a little patient with looking at the answers :)

Actually, if you scroll the the very bottom of this thread you will find there is another link.

You may like it even more :)      It is more attractively presented  wink

For those of you who wonder how I found these, (they are over 3 years old) 

They are in the reference material thread that is in the Sticky Topics :)
