This Is A Party Trick To Surprise Your Friends And Elders.
First Your Friends Are Asked To Write Two Big Numbers Of Their Of Their Choice.On A Sheet Of Paper Or White/Black Board. Say For Example Two Ten Digit Numbers One Beneath The Other.
Now Its Your Turn To Write Another Ten Digit Number Under These Numbers.Again You Friends Will Requested To Write Another Ten Digit Number Under This. Once Again Its Your Turn To Write Another Number Under This; Of Course Ten Digit.
Oh, Every Thing Is Ready For The 'Maths Magic'. Ask Your Friends To Sum Up The Numbers, You Are Lenient Enough To Allow Them To Use Even Calculators. By The Time They Write The First Number On A Sheet Of Paper Or Enter The First Number On Their Calculators You Write The Answer On A Sheet Of Paper And Declare That You Have Summed It Up.
Allow Them To Continue With Their Calculation. When The First One Has Finished Ask For The Answer And Show Its The Same Answer You Have Written Minutes Before.
The Secret.
The Success Of The Trick Lies In The Two Numbers You Have Written. You Will Have To Write Numbers Under Each Digits Such That The Sum Of The Digit You Have Written And The One Just Above( Your Friend Has Written) Is Always Nine. Then The Sum Will Be Nothing But The First Number With A Two In The Beginning And A Two Subtracted From Its Last Digit (Digit At Units Place).
Example.
2 4 5 6 3 7 8 1 6 9
4 7 8 5 2 3 6 4 7 6
5 2 1 4 7 6 3 5 2 3
8 2 4 3 8 7 9 0 1 5
1 7 5 6 1 2 0 9 8 4
2 2 4 5 6 3 7 8 1 6 7
(The Bulleted Are The Numbers Written By Your Friends, And The Numbered Ones Are Written By You. You Can Change The Game By Asking Your Friends To Write Three Numbers One Beneath The Other And Then Writing Your Numbers According To The Rule. You Can Manipulate The Game By Adding More Numbers.)
