The document contains instructions for several math tricks and puzzles involving numbers and arithmetic operations. It guides the reader through steps to solve puzzles such as guessing a randomly selected number, analyzing a person's age, testing if a number is divisible, and arriving at a gray elephant from Denmark. The tricks rely on multiplying, adding, subtracting and doubling numbers in specific sequences.

1. to Math Magic Welcome

2. Power in Numbers Pick a number between 1 and 9 Multiply your number by 9 Multiply your new number by 12,345,679 We will guess your number…

3. Power in Numbers The steps: Pick a number between 1 and 9 Multiply your number by 9 Multiply your new number by 12,345,679 We will guess your number… How it Works The Trick: Simple (or not-so-simple) arithmetic! Note: We multiplied our number by 9 and by 12,345,679

4. Age Analysis Multiply the first number of your age by 5 Add 3 to your new number Double that figure Add the second number of your age to that figure And the result is…

5. Age Analysis The steps: Multiply the first number of your age by 5 Add 3 to your new number Double that figure Add the second number of your age to that figure Subtract 6 from that result And the result is… How it Works The Trick: Another arithmetic trick! Numbers are sooo cool!

6. Do You Feel Lucky? Select a three-digit number Enter it twice in the calculator (e.g. 123123) Double that figure The number is divisible by… The number is divisible by… Do you feel lucky? The number is divisible by…

7. Do You Feel Lucky? The steps: Select a three-digit number Enter it twice in the calculator (e.g. 123123) Double that figure The number is divisible by 11 The number is divisible by your original 3-digit number Do you feel lucky? The number is divisible by 7 AND 13 And the result is… How it Works The Trick: Entering a three-digit number twice (e.g. 123123) is equivalent to multiplying it by 1001. Since 1001 = 11 x 7 x 13, the six-digit number will be divisible by 7, 11, 13 and the original three-digit number.

8. Curious Math Pick a number from 1 to 9 Subtract 5 Multiply by 3 Square the number (that is multiply the number by itself—NOT square root… and yes, you can square 0. 0 x 0 = 0)

9. Curious Math Add the digits until you get only one digit (e.g. 64 = 6 + 4 = 10 = 1+ 0 = 1) If the number is less than 5, add 5 Otherwise, subtract 4 Multiply by 2 Subtract 6

10. Curious Math Map the digit to a letter in the alphabet (e.g. A=1, B=2, C=3, …) Pick a name of a country that begins with that letter Take the second letter in the country name, and think of a mammal that begins with that letter Think of the color of that mammal

11. Curious Math You will be amazed… Are you ready… Here we go… You have a gray elephant from Denmark!

12. Curious Math … or at least you probably have a gray elephant from Denmark. How it Works The trick: The first half of this magical problem is another arithmetic trick. You will (it is certain) map a letter to the number 4 to get “D”). From there we are not certain where you will go, but your answer is quite probable! e.g. You could have selected another country that starts with “D” such as the Dominican Republic or Dominica or Djibouti…but it is not probable. You also could have selected another animal that starts with “E” such as an elk or an ermine…but that’s not probable either : )

13. Math Magic Thank you for attending There are three kinds of mathematicians -- those who can count and those who can't.
