What's between addition and division?

I apologize if my english is not very good, it is not my native tongue.

I have a question that is probably just the resault of ignorance regarding the field.
I fail to see the connection between division and addition. I'll try to explain:

I can add things in "real life". Meaning - I can tell you that 2+3=5, or i can physically (="in real life") give you 2 apples, and then 3 other apples. You will have 5 apples.
so, basically, I can see the connection between addition and multiplication. Multiplication is basically adding the same number to itself several times. So I can say with some confidence the addition = multiplication. They are basically the same thing.
So when I say "five times four", I use the term "times" just to simply the way I say it. So multiplication also exists very well in real life. I have a field that 4km long and 5km wide. I use multiplication in order to calculate the area of my field: 4x5=20. My field's area is 20 square kilometers.
The opposite action of multiplication is division. I can now devide my 20 square kilometers field between 5 nice people. Each of them will recieve 4 square kilomteres. if I choose to give away my 5 apples to 5 people, each will recieve 1 apple. We all know that 20/5=4, and that 5/5=1. So I can say with some confidence that division is basically the same thing as multiplication. They're just opposite actions.

So if addition and multiplication are the same thing,
and also
multiplication and division are the same thing,
does that mean
the division and addition are the same thing?

because I see no connection between the action of, for instance, deviding 5 apples to 5 people, and seeing that each person gets 1 apple, and the action of giving 3 apples to a person and then giving him 5 more apples, giving him 8 apples total.

So, did I get something wrong, or did I just not get something?

20/5 is a quantity such that when we add five of them, we get 20.

20/5 + 20/5 + 20/5 + 20/5 + 20/5 = 5(20/5) = 20

Re: What's between addition and division?

I find it interesting that you would be thinking about this. I work with many college students who don't understand from a simple point of view what multiplication and division even are. They would take your 20 km field and multiply by 5 to split it among your 5 nice people. (No kidding. OK, that's not everyone of course, but there are people who do that.) So I love that you're even thinking about it in this manner. I wish everyone would do this.

Re: What's between addition and division?

The difference is that when you count ones ten times you get ten. When you divide ten by one you. Get ten. I I I I I I I I I I I equals ten. Ten divided by one equals ten so it kind of like a reverse of multipulcation ( but instead I use addition) and division. I think that is the answer it is a bit confusing isn't it.

Well bye hope you like my answer!

P.s. hope u understand and basiclly no there is no connection betweeen addition and division.
