Note: We multiplied our number by 9 and by 12,345,679

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…

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!

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…

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.

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)

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

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

Curious Math

You will be amazed…

Are you ready…

Here we go…

You have a gray elephant from Denmark!

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 : )
