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
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 :)
