U CAN TELL BIRTHDAY OF ANY BODY BY ASKING THIS!! Guess Your Birthday! Step 1) Have them take the month number from their birthday: January = 1, Feb = 2 etc. Step 2) Multiply that by 5 Step 3) Then add 6 Step 4) Then multiply that total by 4 Step 5) Then add 9 Step 6) Then multiply this total by 5 once again Step 7) Finally, have them add to that total the day they were born on. If they were born on the18th, they add 18, etc. Have them give you the total. In your head, subtract 165, and you will have the month and day they were born on!
I had a book as a kid,that had all these mathematical "tricks" to suprise people.. I loved that book LOL
Since step 7 is 'And now add the number of the day you were born on,' the trick lies in simply doing some mathematical adding to the month number, and then undoing it all again to get back to the original.
Ask this to average American and you have lost them at step 2. Unless you offer them calculator before asking them to multiply or add or subtract
nice maths, but then you are asking there month and date, so what is the use! i had a script that used to tell the day of birth if other details where given! most of us know the date, but then the day, monday, tuesday etc we always forget!
I tried the maths and got 313. I was born on March 13th. Hence the answer was right enough. Its really amazing.
