Sneak
some spelling into this math problem.

1.
Select any number.
Write it out as a word; six hundred and six.

2.
Count the letters (but
don’t count spaces or the hyphen); 13.

3.
Write down the number
of letters as a word; thirteen.

4.
Count the letters in
that word; 8.

Count the letters of that word;
eight. The answer will always work down to “4.” So, 5 (letters in eight), five,
4! Do this trick on a calculator with a 10-digit display or work it out on paper.

1.
Choose any number 1
through 9; 8.

2.
Multiply that number by
the magic number – 123,456,789; 8 x 123456789 = 98,765,432

3.
Multiply the answer by 9;
98,765,432 x 9 = 8,888,888,808.

4.
The answer will be a
10-digit number, with nine of the digits the same as the number chosen in step
1.

The answer here will always work out to 1.

1. Ask
another person to choose a number from 1 to 10 without revealing this number;
3.

2. Have
them double the number; 3 + 3 = 6.

3. Add 2
to the result; 6 + 2 = 8.

4. Divide
that number by 2; 8 divided by 2 = 4.

5. Subtract
the original number from the answer in step 4; 4 – 3 = 1.

6. The
answer is always 1.

It seems like magic that the answer always works out to 9.

1. Enter
into a calculator any number that consists solely of the number nine repeated;
9,999.

2. Multiply
it by any number; 9,999 x 25 = 249,975.

3. Write
down the number on paper.

4. Add
the individual digits in the answer; 2 + 4 + 9 + 9 + 7 + 5 = 36

5. Add
the answer digits together. If the answer isn’t 9, repeat adding the new answer
digits until the result is 9
