Zero...
John now has 3 Apples.
You took 2 apples from 3 apples. You now have 2 apples, and there is one left in the bag or wherever you took the 2 apples from.
If there are 10 apples and you take away 2, you would have 8 apples left. However, since you took 2 apples, you now possess those 2 apples. Therefore, you have 2 apples, while 8 apples remain with the original count.
Imagine you have apples that you have put into groups, with each group having 5 apples in it. If you take one group, you have 5 apples. This is the same as 5 x 1. 5 is how many apples per group you have. 1 is how many groups you take. If you take two groups of apples, you have 10 apples. This is the same as 5 x 2. Now consider if you don't take any groups of apples. How many apples would you have? You wouldn't have any. This is the same as 5 x 0.
okay, lets say that you and a friend (two of you) have have an apple tree and each of you pick two apples from the tree, if you count all the apples you have picked you will see that you have four apples in total (two groups of two, 2 x 2 = 4). The next day you and two friends (so now there's three of you) go to the apple tree and pick three apples each. Now if you count all the apples you will see that you have nine apples in total (three groups of three, or 3 x 3 = 9)

I think you mean: is the number zero a member of the set of natural numbers? ie does 0 ∈ ℕ The answer is: yes and no - depending upon which definition you use! The natural numbers are the counting numbers which can be used to count things. eg you can have 1 apple, 2 apples, etc. However, you can also have no apples (0 apples): you had 5 apples and gave them all to your friends and they now have the 5 apples and you have 0 apples. You can't really count zero apples - it is an absence of apples. Hence some definitions include zero, others do not.

All 10 apples are left, but now he only has 8 of them in his possession, and he'll never see the other 2 again.

in apples
Certain varieties of apples have more of a tendency than others to turn brown when cut. Some agriculturists have worked on select breeding for a less-browning characteristic. Also, storage apples will brown quicker than fresh apples. Right now, you should be getting fresh apples in the stores.If you are referring to purchased cut apples, there are preparations - like lemon juice and sulfites - that will reduce browning.
