Homework problem? READ THIS BEFORE POSTING

We will not do your homework for you; it has been given you for a good reason, to help in the learning process. To put it tritely, we learn by doing.

Unless you have been extremely poorly taught, you will have been given, or pointed toward, all the theorems/definitions you require at least to make a start.

But you are struggling, or short of time, so why not ask on a forum?

This is a form of cheating - if it gets you a higher grade than your classmates, it is down-right dishonest. Fundamentally though, you are cheating on yourself, again to put it tritely.

However, at their own discretion, members may be willing to offer help for homework questions, but only under the following conditions:

You must show all your attempts at a solution to date, no matter how foolish they turn out to be. Requests without this content may be deleted - they will certainly be edited to discourage members from helping;

The help you may be offered will (I hope) generally be in the form of hints - think about them carefully and follow up; none us likes whistling in the wind;

Do not pressurize - if your assignment is due in at 8,30 am tomorrow, that's your problem. You cannot expect potential helpers to sit up all night on your behalf;

And finally, remember that any member in a position to help you will have solved your problem (and many others) themselves, generally without help. So be nice - a thank you is always appreciated

The 1. 100-natural numbers' formula.

I'm new and probably a little mathematical stupid, but still only 14 and wanna test how this help thread works. So I'm just gonna pick up an random assignment from my Math textbook, explain it and give my best shot to guess it's logic. I'll leave some question theories if I'm able to, but don't expect them to be any smart or cleverly guessed.

Explanation: The mathematical genius Carl Friedrich Gauss (1777 - 1855) found in young age a formula to sum up the first hundred natural numbers. The sum turns out to be 5050, but then - what's the formula?

Eh, my theory, well ah . . . Need som bright assistance here :oops:

(It's not very important, I'm just here to improve my math skills a bit if possible, so all theories are welcome. I'll post mine later, but I just can't think of any at the moment . . . :oops:

Maybe 1 x 2 x 3 x etc. ? :oops: 1 x 10 x 20 x etc. :oops: (Poorly taught + a bit fogged up :P)

I ask only for hints, of course.

100(100+1)/2

= 10100/2

=5050

therefore the formula is n(n+1)/2 where n is a positive integer. (in your case 100)
