Combining your mastery of math with a bit of magic is possible through mathematical mind reading tricks.
Step 1: Ask them to think of a number from 0 to 9.
Let's say 2.
Step 2: Tell them to double the number.
The numbers are 2+2=4.
Step 3: Tell them to add five.
The numbers are 4+5 and 9.
Step 4: Tell them to add five to the answer.
9*5 is 45.
Step 5: Tell them to remember.
45 is the number.
Step 6: Ask them to pick a different number.
In this case, 4.
Step 7: They should add this number to their answer.
45+4 is equal to 49.
Step 8: They can give you the answer.
It was 49.
Step 9: Take 25 out of the total and listen to it carefully.
49 25 24
Step 10: The first digit of the answer you remember is the first number they picked, and the second digit is their second number.
Step 11: Understand the math behind the trick.
The answer should be the same no matter what you start with.If you follow the instructions starting with the variable X instead of the actual number, you will see that X is eliminated by adding the example's number 17
Step 12: This trick can be done with a magician's patter.
Ask the crowd for suggestions for the "original number", which could be anything from someone's age to their favorite number.This will change the outcome.
Step 13: The trick should be performed.
Think of a positive number.You can do computations in your head if you keep it small.It should be square.You can add the result to your number.Divide by the original number.How about 17?Take your original number and subtract it.Divide by six.The number you are thinking of is 3.
Step 14: You can make a magic number trick.
You can make your own mental math trick with this idea.Don't tell people to add 5, subtract their original number, or say "the number you are thinking of is 5"
