Richiez: This thread is the meeting point for nairaland maths gurus...i dare you all to ask me a question in mathematics without me having an answer to them, LETS START

Great mathematician, I hail o.
We have this little problem that has been bothering us
for sometime;

Take any positive integer n. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to obtain 3n + 1. Repeat the process.

For example let's take 6, an even number, 6/2 =3, 3 is odd so we multiply it by 3 and add 1 to obtain 10,
10/2=5, 5 is odd, multiply it by 3 and add 1 to obtain 16, 16/2=8, 8/2=4, 4/2=2, 2/2=1.
We ended up with 1.

Now let's start with 3, an odd number,(3 * 3)+1 =10, 10/2=5, (5 * 3)+1 =16, 16/2=8, 8/2=4, 4/2=2, 2/2=1.
We also ended up with 1.

The problem is can you help us find a starting number that will not end up with 1
after going through the process. You can use a proof or something, or you can
give a mathematical proof that any starting number will always yield 1 in the end.

Thank you.

When I switch over from holiday mode, I hope
to continue work on a custom Q and A site
I abandoned a few years ago.

Nice job. Kudos.

Ive been trying to do a webpay integration,
in the final stage where I have to query the
web service, I've been trying to do that with CURL
but I either get no response or an error message.

It seems one needs to know more than what is in their
documentation to get the thing working, we've been corresponding
but they don't seem to appreciate the problem.

Has anyone successfully integrated interswitch - to give
some lead....thank you.

Wahooo. That was my main snack back in the day,
especially the four-cornered variety, you'll
always find the nylon in my pockets.

The interesting numerical facts about number 9
stem from the fact that we use the base 10 number
system(we count in 10's), 10-1 = 9.

If you use any other base, let's say base b, you'll
get the same interesting results for the number b-1.
I have a simple proof for this but 2busy to state it
now. But let's take an example :

Using base 4, b-1 = 3

3 X 2 = 12
3 X 3 = 21

The sum of the resulting digits 1+2 = 3.
Likewise, 2 + 1 = 3

Look into the CSS float property. Google it.

dmark4real: i need the page to automatically calculate and display the amount when the quantity and rate is selected without having to click anything. I hope anyone understand this.

You will need JavaScript to do that, look into the JavaScript onBlur event.

Waoooh. Brilliant, beautiful, confident.

Hello folks, I need to get some 'snapshots' out of a video recording
to use on a website, I wanted to post this in the webmasters section but
thought the graphics gurus will know better - what's the best way to
achieve this.

Nigeria is 52. Still in the spirit of the anniversary,
we are are giving out 52 sms units free each to the
first 20 people to request for them, so you can use
them to market your business.

Just sign up at www.supertextng.com, confirm your
registration, then drop your registered username here.

You get 5 free units automatically on registration but
you have to drop your username here so we can add the
bonus 52 units, making a total of 57 units. For the first 20
only.

We can do that for you, check the link in my sig
for contact details.

Can you explain more how the game is played,
is the guessing consecutive for a player, I mean,
does a player guess 5 times consecutively...?

Why not go check out various schools in Ikeja
and see what they have to offer as per programmes/
content/duration/cost and then make your choice.

1. It appears you wear glasses
2. It appears you lack sense of humour

I found this on FB.
LWKMD.

databoy247: so how do we make it "whole" ?

I guess, unzip the two folders and merge their contents,
then zip the new combo folder.

Very professional work, naija is blessed!

@ pc guru, you'r welcome.

21 Businesses You Can Run From a Laptop

Maybe you’re a young kid who wants to start a business. Maybe you’re a college grad who wants to create a job (rather than finding one). Or maybe you’re a corporate mouse who’s fed up with the rat race.

In any case, the internet has opened up a world of opportunities for the entrepreneur-at-heart. Here are 21 businesses that you can start today and run entirely from a laptop and an internet connection.

#1 Web Developer

According to SBA.gov, there were 29.6 million small businesses in the US and Ad-ology found that 46% of small businesses don’t have a website.

#2 Mobile App Developer

In 2010, the International Telecommunication Union reported that there are over 5 billion cell phones in the world and 1 billion of them have mobile broadband subscriptions.

#3 Blog Maintenance Provider

As tracked by BlogPulse, there were 126 million blogs on the internet in 2010 and most of them suck. Most bloggers think they just have to write, post, and auto-tweet. So if you know how to properly post a WordPress blog post, you can offer this as a service to serious bloggers.

#4 Logo Designer

Since there are 29.6 million small businesses in the US alone, that’s 29.6 million potential logo customers. But most of them already have logos… Yeah, but very few of them have good logos.

#5 Web Designer

According to Pingdom, there are 234 million websites on the net. Like small business logos, most of these websites look terrible. And even the good ones, as you’ll soon see on Retire@21, know the value of continually improving the design.

#6 Book Cover Designer

Right now, there are over 32 million books on Amazon and every one of them has a book cover. According to UNESCO, over 1 million books are published per year. This doesn’t include eBooks.

#7 Mobile App Designer

Much like mobile app developers, there’s plenty of need for mobile app designers. Companies usually contract out to both developers and designers separately to create the app.

#8 Computer-Aided Designer

CAD drawings are typically 3D mockups and virtual prototypes that companies create prior to manufacturing a product. Pretty much every product design starts as a CAD drawing.

#9 Web Theme Designer

According to , there are over 53 million WordPress sites and about half of them are self-hosted. This means, WordPress alone has about 26 million sites that need themes.

#10 Videographer

In 2009, Zappos reported a 6% to 30% increase in sales for products with video. Website owners realize that video converts higher than any other form of content, so they’re starting to contract out for that work.

#11 Author

According to Authors Guild, a successful fiction book sells 5,000 copies and a successful nonfiction book sells 7,500 copies. Also, Jenkins Group (a premier publishing firm) reports that 70% of books published don’t make a profit. Don’t let these stats discourage you, but it’s hard to make a living as an author.

#12 Editor

Part of the reason books usually don’t earn back their investment is because they have to pay for an editor. You’ll likely earn more as an editor than an author.

#13 Copywriter

With 126 million blogs, there are 126 million websites that need content. If you’re a good writer and knowledgeable about a niche topic, reach out to the top bloggers in that niche and ask if they’ll pay you to write for them.

#14 Transcription

According to Worldwide Freelance, some industry estimates suggest that up to 50% of all non-fiction books are ghostwritten. Often, these books start as audio recordings and the ghostwriter transcribes and spruces up the content. This is just one way to make money as a transcriber.

#15 Translation

English is the universal language of business, but there are roughly 6,500 other languages in the world. Books, websites, manuals, etc. all need to be translated to other languages.

#16 Blogger

Much like authors, few bloggers make a living strictly from blogging. To attract advertisers, you typically need a couple thousand unique visitors per day. Think of a blog as a platform to attract other business opportunities.

#17 Search Engine Optimization

234 million websites compete to rise to the top of search engines. If you know how to optimize websites, you can help website owners save a lot of money on internet advertising.

#18 Search Engine Marketer

The other side of search engines is paid search. It’s not unusual for internet marketers to have $500,000 per month budgets for PPC (pay-per-click) and CPM (cost-per-thousand-impressions) advertising.

#19 Social Media Manager

Don’t let companies outsource their social media campaigns. But a service that helps people set up their Facebook, Twitter, and Google Plus profiles is completely legitimate.

#20 Email Marketing Manager

Michael always tells you that the money is in the list, but it takes a lot or work to maintain that list. If you offer to create and automate the email newsletters, it’ll take a lot of pressure off their backs.

#21 Affiliate Marketer

To date, ClickBank has paid out almost $1.9 billion to affiliate marketers. Affiliate marketing is another way to make a living as a blogger and it’s the primary way that Michael makes money.
