- 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
- 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
- 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
- 8. Curious Math
- Try this and you will be amazed
- Follow the rules
- And do not cheat
- Just do it step-by-step
- Here we go
- 9. Curious Math
- Pick a number from 1 to 9
- Subtract 5
- Multiply by 3
- Square the number
- 10. 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
- 11. 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
- 12. Curious Math
- You will be amazed
- Are you ready
- Here we go
- 13. 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!
- 14. Math Magic Thank you for attending There are three kinds of mathematicians -- those who can count and those who can't.
