# How many solutions do the equation have

Hello,

I have a discrete math problem. It states how many solutions (X_1,...,X_6) in the Natural numbers have the equation X_1+ ... + X_6 = 10

So the way my teacher explained it was (10,0,0,0,0,0) would be one choice, (0,10,0,0,0,0) would be another, so basically it would look like this...

(10,0,0,0,0,0)

(0,10,0,0,0,0)

(0,0,10,0,0,0)

````````````````

(0,0,0,0,0,10)

THEN you have other solutions like

(1,9,0,0,0,0)

(0,1,9,0,0,0)

```````````````

(0,0,0,0,1,9)

And keep going until all the combinations of numbers are found.

I see that each, i suppose you would call them sets, have 6 combinations. So like (10) has 6, (1,9) has 6, ... you could do (1,1,8), or (1,1,1,7), or whatever else combinations. I just don't understand how to determine how many combinations there are.

Any help would be appreciated.
