The Birthday Breakdown Trick
You have your audience ready, goodie.
Now is the time to workout the persons birthday. Ask for a volunteer.
Ask the volunteer to write the number of the month that they were born. Eg April is the 4th month
-
Get them to multiply that by 4
Eg 4×4 = 16
-
Add 13 to the new number
Eg 16 + 13 = 29
-
Now multiply that by 25
29 x 25 = 725
-
Subtract 200 from the new amount
725 – 200 = 525
-
Add the day of the month they were born
525 + 2 = 527
-
Multiply that new number by 2
527 x 2 = 1054
-
Subtract 40 from the new number
1054 – 40 = 1014
-
Multiply that new number by 50
1014 x 50 = 50700
-
Get them to add the last two digits of the year your were born (1971)
50700 + 71 = 50771
-
Ask the volunteer for the answer.
50771
