You see plates.
Let's find out how many apples are on two plates?
There are three apples on the first plate,
on the second plate there are no apples.
You already know that in math, when there are no objects, we write the number zero.
So, on the second plate there are zero apples.
Let's write the equation:
add zero to three, we get three.
So, on two plates there are three apples in total.
Remember!
If you add zero to a number, you get the same number.

Look,
there were four cookies on the plate.
After some time, four cookies were eaten.
How many cookies are left on the plate?
We see that there are no cookies on the plate now.
