Dr. Nwabueze Trick
Dr. Nwabueze came early to his lecture class. Usually he came late which was unusual for that day. And usually he came with his escort, three bodyguard. His bodyguard sat at the back lecture hall. They wore smart dress and if it's not at night time, some of them use black glasses. But unfortunately, despite of being early to class, not much students attended his class on that day. He had to cancel his class since it's no use to teach few students. Before he left the class, he showed a maths trick. He called a student to come infront and let that student wrote some number on the white board.
That student which was a girl wrote 3-digits number.
That girl wrote 135
Then, Dr. Nwabueze wrote 2133 on the right side of the white board. He told that student to wrote 3-digit number below it again.
That girl wrote 135
That girl wrote 888
Dr. Nwabueze wrote his no. below it.. and so and so.
That girl wrote 135
That girl wrote 888
Dr. Nwabueze wrote 111
That girl wrote 780
Dr. Nwabueze wrote 219
They wrote that 5 numbers in a short time and Dr. Nwabueze asked his students to calculate the total. Surprisingly, the ans was 2133!! The same number he wrote on the right side of the white board.
Ok, let me unlock his trick. The process works like this. Dr. Nwabueze minus the last digit with 2 and then add 2 infront of the whole digits.
Eg. 46623 (5-digit), the last digit is 3. So deduct 2 from it. It becomes 46621. Then add 2 infront of the whole digits. It becomes 246621. This is the ans. So ask anyone to write 5-digit no. again.
Anyone 46623
Anyone 12738
It's your turn to write 5-digit number. Make sure the total is 9 for every digit. It goes like this.
Anyone 46623
Anyone 12738
You 87261
Anyone 55613
You 44386
Ask them to sum up. Is it 246621? Such a wonderful trick.

Hehe.. u can find Dr. Nwabueze in UBD with his three tough bodyguards. This story is real la, not myth or fiction.. :-D.
It seems that ur maths brain is still working.. congratulation.. :-D. Hehe.. use 'borrow' method u learned in kingergarden la.. remember it?? Or was u playing during that old day??!!
Ok.. look here little kid, Eg.
for 21471, the ans is 221469

for 8200, the ans is 28198
for 74501, the ans is 274499
U know, what he did was the addition of five numbers. It's possible to create a formula of addition to 7, 9... (n+2) number.
Eg. for 61527, the ans is 361524 for the total of seven numbers.
Ppl 61527
