Politics / Re: Are Nigerian Youths Actually Lazy? by DanitoA1(m): 2:21pm On Apr 19, 2018
Is not surprising that bihari could say such about the Nigerian youths, since he once said such about his wife in similar abroad meetings. Truth is there's atom of truth in his speak but that's equally not the best way to present your country to the international community. Is not completely cool, but we must really stand to our feet as youth to prove him wrong, am sure he wasn't trying to insult anyone. Is just his own wrong way of saying some kind of truth. He is old and had helped himself during his youthful age, as it was in their time when youths were the leaders of almost every decision making body, we as youth must stand up and stop assuming this guys hates us, they really don't, they just love power a little more, greed is almost natural it takes been disciplined and principled to stay true to the right values.

Investment / Re: Scary Investment For Real Investors Ethereum by DanitoA1(m): 5:45pm On Feb 05, 2018
You can actually trade by yourself, start today to build your financial future, with learning how to trade binary options and make daily consistent profit of between $200 to $250 working just 4hrs daily, well as easy as it sound it is real but would take lot of dedication and patient to make it work.
And it would require a capital of not less than $450-$500 (i.e about 200k naira) if interested pm me. You don't have to pay a dime to learn, but of course you would have to pay when you start making consistent profit. You would never be asked to transfer any money to me except by your own free will after learning and practicing what I would teach you. Contact me. Please only serious people. 08148023216

True talk trading currency online is risky when you not sure what you're doing, I repeat very very risky.
einsteine:


Open an account on Binance and trade away. You are as likely, if not more likely, to lose your money as to make money if you don't know what you are doing.
Career / Re: I Want To Quit My Job And Live On My Savings by DanitoA1(m): 5:10pm On Feb 05, 2018
Nice gist has been going on about investment and Job stuffs. Well apart from bitcoin and other cryto currency you can actually learn to trade binary options and with a reasonable amount of capital, you can be making up to an average of $250 working just 4hrs daily. The strategy for doing this is actually easy to learn but takes a bit of dedication and patience to make consistent profit am willing to teach anyone interested and actually has at least 450 to 500$ (about 200k in Naira) capital to invest.
You would not pay to learn, you would only pay after you start making consistent profit.
It would benefit you more if you stay in Lagos, because you would have the opportunity to meet me one on one.
Contact me if you are interested between 6pm to 10pm only please. 08148023216 or chat on WhatsApp only serious people please.

Become A Human Calculator, Solve Calculations Without Calculators

Learn how to solve calculations without the use of your calculator.
It is no longer a news that the trends of exams are changing, the use of calculators has been scrambled from many examination platform both at secondary and tertiary levels and so it is expedient to know how to solve very fast without the use of a calculator.
Below are some few examples of what the main package contains:

 Multiplication by 11

To multiply 52 and 11, imagine there is a space between 52


52*11= 5_2 (Put an imaginary space in between)

Now, lets fill the space;

Just add 5 and 2 and put the result in the imaginary space


So, 52 * 11 =572 (which is your answer)


Isn't it great?

Let’s try some more examples:


1) 35 * 11 = 3 (3+5) 5 = 385

2) 81 * 11 = 8 (8+1) 1 = 891

3) 72 * 11 = 7 (7+2) 2 = 792 etc..
With just a little bit of practice you can easily perform these simple mental maths tricks in the blink of an eye.


 Multiply any large number by 12 mentally in seconds

To multiply any number by 12 just double last digit and thereafter double each digit and add it to the next and right each result:
I know it sounds boring and senseless, just check the examples below to get it clearly;

For example 21314 * 12 = 255768

Let’s break it into simple steps:

Step 1: 021314 * 12 = _____8 (Double of Last Digit 4= 8 )

Step 2: 021314 * 12 = ____68 (Now Double 1= 2, and add it to 4, 2+4=6)
Step 3: 021314 * 12= ___768 (Now Double 3=6, and add it to 1, 6+1=7)

Step 4: 021314 * 12= __5768 (Now Double 1=2, and add it to 3, 2+3=5)

Step 5: 021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

Step 6: 021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of 21314 * 12 = 255768


 Is 456138 divisible by 9?

Now, it only takes 2 seconds for you to determine the answer. But if you go by the traditional way then it will take you 10 seconds. So you can see the difference. Those 8 extra seconds you win, you can spend on other question. Isn't it?

No let see the solution

(Answer) To test whether a certain large number is divisible by 9 or not, 'just add all the digits of the number and if the end result is divisible by 9, then you can say that the entire large number will be divisible by 9 too'.

4+5+6+1+3+8=27

Now since 27 is divisible by 9 so 456138 will be divisible by 9 too.

 Calculating Square of numbers quickly...
Squaring numbers is quit easy check the examples below:
Lets calculate the square of 54

So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916

Similarly (55)^2 = 5^2 +5 --5^2=25+5------25=30---------25= 3025

Similarly (56)^2 = 5^2 + 6--6^2=25+6------36= 31--------36= 3136 etc..

Similarly try out squares of 57, 58 etc..

Some of this might not make full sense to you for now, but I can assure that with the full Amazing mathematics Tricks E-book would give you all the explanations you need in a simple and clear way, try it out following the link below to get on Okada online book store:

Step 5: 021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

Step 6: 021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of 21314 * 12 = 255768


 Is 456138 divisible by 9?

Now, it only takes 2 seconds for you to determine the answer. But if you go by the traditional way then it will take you 10 seconds. So you can see the difference. Those 8 extra seconds you win, you can spend on other question. Isn't it?

No let see the solution

(Answer) To test whether a certain large number is divisible by 9 or not, 'just add all the digits of the number and if the end result is divisible by 9, then you can say that the entire large number will be divisible by 9 too'.

4+5+6+1+3+8=27

Now since 27 is divisible by 9 so 456138 will be divisible by 9 too.

 Calculating Square of numbers quickly...
Squaring numbers is quit easy check the examples below:
Lets calculate the square of 54

So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916

Similarly (55)^2 = 5^2 +5 --5^2=25+5------25=30---------25= 3025

Similarly (56)^2 = 5^2 + 6--6^2=25+6------36= 31--------36= 3136 etc..

Similarly try out squares of 57, 58 etc..

Some of this might not make full sense to you for now, but I can assure that with the full Amazing mathematics Tricks E-book would give you all the explanations you need in a simple and clear way, try it out following the link below to get on Okada online book store:

DON''T JUST GAIN ADMISSION LEARN SOME TRICKS TO STAND OUT
Become A Human Calculator, Solve Calculations Without Calculators
Learn how to solve calculations without the use of your calculator.
It is no longer a news that the trends of exams are changing, the use of calculators has been scrambled from many examination platform both at secondary and tertiary levels and so it is expedient to know how to solve very fast without the use of a calculator.
Below are some few examples of what the main package contains:

 Multiplication by 11

To multiply 52 and 11, imagine there is a space between 52


52*11= 5_2 (Put an imaginary space in between)

Now, lets fill the space;

Just add 5 and 2 and put the result in the imaginary space


So, 52 * 11 =572 (which is your answer)


Isn't it great?

Let’s try some more examples:


1) 35 * 11 = 3 (3+5) 5 = 385

2) 81 * 11 = 8 (8+1) 1 = 891

3) 72 * 11 = 7 (7+2) 2 = 792 etc..
With just a little bit of practice you can easily perform these simple mental maths tricks in the blink of an eye.


 Multiply any large number by 12 mentally in seconds

To multiply any number by 12 just double last digit and thereafter double each digit and add it to the next and right each result:
I know it sounds boring and senseless, just check the examples below to get it clearly;

For example 21314 * 12 = 255768

Let’s break it into simple steps:

Step 1: 021314 * 12 = _____8 (Double of Last Digit 4= 8 )

Step 2: 021314 * 12 = ____68 (Now Double 1= 2, and add it to 4, 2+4=6)
Step 3: 021314 * 12= ___768 (Now Double 3=6, and add it to 1, 6+1=7)

Step 4: 021314 * 12= __5768 (Now Double 1=2, and add it to 3, 2+3=5)

Step 5: 021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

Step 6: 021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of 21314 * 12 = 255768

(Answer) To test whether a certain large number is divisible by 9 or not, 'just add all the digits of the number and if the end result is divisible by 9, then you can say that the entire large number will be divisible by 9 too'.

4+5+6+1+3+8=27

Now since 27 is divisible by 9 so 456138 will be divisible by 9 too.

 Calculating Square of numbers quickly...
Squaring numbers is quit easy check the examples below:
Lets calculate the square of 54

So (54)^2 = 5^2 +4 -- 4^2 = 25 +4 ----16 =29-------16= 2916

Similarly (55)^2 = 5^2 +5 --5^2=25+5------25=30---------25= 3025

Similarly (56)^2 = 5^2 + 6--6^2=25+6------36= 31--------36= 3136 etc..

Similarly try out squares of 57, 58 etc..

Some of this might not make full sense to you for now, but I can assure that with the full Amazing mathematics Tricks E-book would give you all the explanations you need in a simple and clear way, try it out following the link below to get on Okada online book store:

DON''T JUST GAIN ADMISSION LEARN SOME TRICKS TO STAND OUT
Become A Human Calculator, Solve Calculations Without Calculators
Learn how to solve calculations without the use of your calculator.
It is no longer a news that the trends of exams are changing, the use of calculators has been scrambled from many examination platform both at secondary and tertiary levels and so it is expedient to know how to solve very fast without the use of a calculator.
Below are some few examples of what the main package contains:

 Multiplication by 11

To multiply 52 and 11, imagine there is a space between 52


52*11= 5_2 (Put an imaginary space in between)

Now, lets fill the space;

Just add 5 and 2 and put the result in the imaginary space


So, 52 * 11 =572 (which is your answer)


Isn't it great?

Let’s try some more examples:


1) 35 * 11 = 3 (3+5) 5 = 385

2) 81 * 11 = 8 (8+1) 1 = 891

3) 72 * 11 = 7 (7+2) 2 = 792 etc..
With just a little bit of practice you can easily perform these simple mental maths tricks in the blink of an eye.


 Multiply any large number by 12 mentally in seconds

To multiply any number by 12 just double last digit and thereafter double each digit and add it to the next and right each result:
I know it sounds boring and senseless, just check the examples below to get it clearly;

For example 21314 * 12 = 255768

Let’s break it into simple steps:

Step 1: 021314 * 12 = _____8 (Double of Last Digit 4= 8 )

Step 2: 021314 * 12 = ____68 (Now Double 1= 2, and add it to 4, 2+4=6)
Step 3: 021314 * 12= ___768 (Now Double 3=6, and add it to 1, 6+1=7)

Step 4: 021314 * 12= __5768 (Now Double 1=2, and add it to 3, 2+3=5)

Step 5: 021314 * 12= _55768 (Now Double 2=4, and add it to 1, 4+1=5)

Step 6: 021314 * 12= 255768 (Now Double 0=0, and add it to 2, 0+2=2)

So your final answer of 21314 * 12 = 255768
