:: How to Do a Cool Mathematical Mind Reading Trick ::

You ask the spectator to pick a number from 0 to 9 in his/her head. Later on after some steps they pick another number from 0 to 9. After one more step they tell you the answer and you can tell them the two numbers they picked in the same order!

Steps

Ask them to pick a number in their mind from 0 to 9. ( Let's say 2 ).
Tell them to double the number. ( 2+2=4 ).
Tell them to add five to the new number. ( 4+5=9 ).
Tell them to multiply the answer by five. ( 9*5=45 ).
Now tell them to remember the answer. ( 45 ).
Ask them to pick another number from 0 to 9. ( in this case 4 )
Ask them to add this number to their answer. ( 45+4=49 ).
Ask them to tell you the answer. ( 49 ).
Listen to it carefully and then in your mind subtract 25 from the total. ( 49-25=24 )
The first digit of the answer YOU get in your mind after subtracting 25 ( 24 ) is the first number they picked ( 2 ) and the second digit is the second number they picked ( 4 ).
