digitaltrades: Then maybe you want to explain why sinators still Budget 5.5 billion naira for cars under APC.
Or explain how Yusuf buhari got money to buy his power bike
Or explain why ajimobi's wife got mixed up in money laundering.
Stop placing political party above your reasoning. It will make you appear dumb First, APC is not my party. Sai bubu, but may my former state governor burn in hell, though, unfortunately I'm cursed with him again in my Alimosho Local Government! But as I've said: budaatum: No one said corruption is not going on under Buhari, after all, Buhari is not every Nigerian and I doubt he can stop you being corrupt. Good thing is your corruption is not in ghanamustgo bags or stored in your soakaway as we will arrest you if you try it. That's why you are wailing, isn't it? As for why senators get paid so much, I'm sure you voted too. If you don't want those who earn so much, perhaps be responsible and elect responsible senators next election. |

Chika’s Test
Something very exciting happened last Friday when one of my pupils, Chika Ofili, popped into the classroom and asked if he could tell me something he had thought of over the summer holidays. I was intrigued.
I had given him a book called First Steps for Problem Solvers (published by the UKMT) to look at over the holidays and inside the book was a list of the divisibility tests, which are used to quickly work out whether a number is exactly divisible by either 2, 3, 4, 5, 6, 7, 8 or 9 before you actually start dividing. Except that there was no test listed for checking divisibility by 7. The reason why it was missing is because there is no easy or memorable test for dividing by 7, or so I thought!
In a bored moment, Chika had turned his mind to the problem and this is what he came up with. He realised that if you take the last digit of any whole number, multiply it by 5 and then add this to the remaining part of the number, you will get a new number. And it turns out that if this new number is divisible by 7, then the original number is divisible by 7. What an easy test!
For example, take the number 532
53 + 2 x 5 = 63 63 is a multiple of 7, so 532 is a multiple of 7 (and therefore divisible by 7)
Or take the number 987
98 + 7 x 5 = 133 13 + 3 x 5 = 28 28 is a multiple of 7, so both 133 and 987 are multiples of 7
In fact if you actually keep going, you will always end up with either 7 or 49, if the original number is divisible by 7.
For example, take the number 2996
299 + 6 x 5 = 329 32 + 9 x 5 = 77 7 + 7 x 5 = 42 4 + 2 x 5 = 14 1 + 4 x 5 = 21 2 + 1 x 5 = 7
7 is a multiple of 7 and so is 21, 14, 42, 77, 329 and the original number 2996.
The opposite is also true in that if you don’t end up with a multiple of 7, then the original number is not divisible by 7.
For example, take the number 114
11 + 4 x 5 = 31 3 + 1 x 5 = 8
And since 8 is clearly not divisible by 7, neither is 31 nor our original number 114.
Chika demonstrated his test to 8E before lunch on Friday and no one could find a counter-example to disprove it. But mathematically we needed to find a proof. Once a theorem is proved mathematically it will always be true. Pythagoras proved his famous theorem over 2500 years and when he died, he knew it would never be disproved. It is important to realise that a result cannot be proved by finding thousands or even millions of results which support it.
I woke up early on Saturday morning still thinking about Chika’s test and rang my younger brother, Simon Ellis, who also happens to teach Maths, and asked him if he had ever come across the test. He hadn’t and immediately set about trying to write a proof. An hour later he sent me a watertight algebraic proof! He also discovered that the test works if you start by multiplying the last digit by 12, 19, 26, 33 … and then add it to the remaining part of the number. And furthermore, it works if you double the last digit and then subtract it from the remaining part of the number, of if you multiply the last digit by 9, 16, 23, 30 … and subtract. And actually the doubling and subtracting test can be easily found on the internet.
But we both agreed multiplying the last digit by 5 and adding it to the remaining part of the number is much more appealing! Mr O’Donnell urged me to tell the school about Chika’s discovery, so an impromptu demonstration followed in Monday’s assembly. We are now trying to figure out how to make this test more widely known, as it is so simple that it really should be taught alongside the other divisibility tests.
For all those interested, the proof can be currently found on my brother’s website: www.simonellismaths.com/post/new-maths
Also, to be entirely accurate, the test for divisibility by 6 was also missing from the book but this is because you only have to apply both the divisibility by 3 test and divisibility by 2 test (as 2 and 3 are coprime) to a number to determine if it is divisible by 6.
And finally thank you to Stephan for telling me on Tuesday about a Russian test, which involves multiplying the truncated number (without its last digit) by 3 and then adding the last digit. It does work but it is harder on the whole. So for example, take 154: 15 x 3 + 4 = 49, so since 49 is a multiple of 7, so is 154. |

Stop lying! Rankadede is not work! digitaltrades: If you are accustomed to the proper use of the brain, you would have realised that people were working before eating even before buhari became president.
But it looks like you intentionally shut down your brain. If not, you would have realised that the economic difficult brought upon Nigerians by buahri means that people have to work double to achieve the same result. And do you know why? Because your country's currency has become so poor that a bag of rice now costs more than half of minimum wage. Does that ring a bell in your brain?
Oh sorry.... The question should be do you even have adequate mental capacity to process that information? |

Before him you just did rankadede and were fed. It is not Buhari who will better your economy. He never promised to put food in your mouth. This is next level 4+4 when lazy fuqs must starve! budaatum: They are not chopping like they used to under GEJ. In GEJ time, I could not get them to come work on my farm because they earned so much more than I could pay doing rankadede to the local politicians. Nowadays, they beg me to give them gari because rankadede doesn't pay anymore and they starve. budaatum: 21 million loot sharers who have no loot to share are not 21 million jobs lost.

Goto every junction and see abokis begging , they now enter Street because of what LIFELESS DULLARD 
Do your research well mate !!! I'm certain bubu is not the President of Northern Nigeria, and lazy asses beg all over Nigeria and have done so forever. It's the lesson most learn in their holy places, "Raise up your voice to the Lord and manna will drop from the heavens"! Thing is, you can tell dissatisfied nations by their citizens demanding change by raising protests on the streets. We Nigerians are not starving, yet, that's for sure. But serious. Instead of begging here, you can surely just step out your door and do something. It's what I did in my hard times. budaatum: Yes I have had the experience of feeling hunger that pains muscles though, usually, I do something reasonable about my hunger before my muscles hurt and I do "almost anything".
I once went to mama put and started washing plates not daring to clear tables myself least she think I wanted to eat the leftovers. Afterwards, she gave me 30kobo eba with a 10kobo fishhead but I told her I don't want the fish head and can she let me take 10kobo eba home for supper. She gave me 30kobo eba with the fishhead and asked if I'd be back the next day.
One day I went to the Lagos end of L-IER tollgate to help a friend sell eggs. Friend gave me one egg for every 10 I sold and after a week I had enough to buy and sell my own eggs before graduating to selling 50kobo iced canned cokes.
I wasn't a graduate of primary school then so imagine what I did when I graduated proper. |
