This document contains instructions for several math tricks and puzzles. The tricks involve having a person perform simple math operations like multiplication, addition, and subtraction based on numbers like their age, birthdate, or numbers rolled on dice. The final result is then used to reveal something like the person's age or numbers rolled on dice.

- 1. + MATH TRICKS Some example
- 2. + "There are no Elephants in Denmark!» Pick a number between 1 & 10. Multiply by 9. If the result is a two digit number, add the two digits together. Subtract 5 from the resulting number. Beginning with the letter A as 1, count over in the Alphabet that many letters ( I usually will count a few out loud " A is 1, B is 2, C is 3.") Now think of a Country that begins with your letter (Only big Baseball fans, or Cigar smokers will get the Dominican Republic, the rest will get Denmark) Take the second letter in your county and think of a Circus Animal that begins with that letter. Wait a couple of seconds and say "There are no Elephants in Denmark!"
- 3. + Finding Someone’s Age Ask the person to multiply the first number of his or her age by 5. Tell them to add 3. Now tell them to double this figure. Finally, have the person add the second number of his or her age to the figure and ave them tell you their answer. Deduct 6 and you will have their age.
- 4. + Math trick 1 Think of a number. Add 3. Double that. Subtract 4. Cut that in half. Subtract your original number. Your result is 1!
- 5. + Math trick 2 Write the year of your birth. Double it. Add 5. Multiply by 50. Add your age. Add 365. Subtract 615. The first four digits are the year of your birth. The last two digits are your age.5
- 6. + Math trick 3 1) Write down the number of the month they were born on. 2) Multiply by 100. 3) Add the day of the month they were born on. 4) Multiply by 2. 5) Add 9. 6) Multiply by 5. 7) Add 8. 8) Multiply by 10. 9) Subtract 419. 10)Add his age. 11)Subtract 111. The 2 digits on the right is the person’s age. The 2 digits on the left from the person’s age is the day that they were born on. The numbers that are left are the month your friend was born in.
- 7. + Old Enough 1)Write down your age (actually you can just write down any number if you want). 2) Multiply it by 3. 3) Add 1 to the total 4) Multiply that by 3 5) Add the original number (your age) Then you ask for the total. Suppose that someone writes down 23. They multiply it by 3 getting 69. The person adds 1 getting 70. It is multiplied by 3 equaling 210 and the original number is added which equals 233. When you are told this number you take away the last digit. This gives you 23, which is the original number.
- 8. + Have a Roll You will need 3 dice. Give the person 3 dice saying, “When my back is turned please roll these 3 dice.” Now tell the person these directions: 1) Multiply the number on die one by 2. 2) Add 5 3) Multiply by 5 4) Add the number from die 2 to the total 5) Multiply by 10 6) Add the number on die 3 to the total Finally say, “What total did you get?” You subtract 250 from the number. Suppose the person tells you 612. 612-250=362. So the numbers showing on the dice are 3, 6, and 2
