You do not need to see the paper, you only need to know the final answer!!
Material needed :Paper and Calculator
Write the question on the paper and tell him or her to work out!
1.Write down the month he or she was born (January=1, February=2 ,etc)
2.Multiply this number by 2
3.Add 5 to it
4.Multiply the result by 50
5.Add his age to it
6.Take away 250
(The First digit is the month the person was born,the last two digits will be his age.)
exp:(122=born in january ,22 years old) (1010=born in obtober, 10 years old)
Example for me: 1. September=9
2. 9 multiply 2=18
3. 18+5=23
4. 23 multiply 50= 1150
5. 1150+ 16=1166
6. 1166-250=916
So i am born in september, 16 years old
