Using a calculator, input a 3 or 4 digit date. (Example: May 7th = 507, December 25th = 1225).
Next, do the following:
multiply the number by 2 add 7
multiply that number by 50 add any 2 digit number
Take the calculator and subtract 350 from the number on the screen.
The first 3 or 4 digits is the date in step one;
and the last 2 digits is the number chosen in the last step.
PICK A NUMBER:
Pick any 1 or 2 digit number (just make sure it isn't '0').
Multiply that number by 99.
Add up all the digits in your answer and the sum will be 18.
THREE DIGIT REVERSAL:
Pick any 3 digit number then reverse that number placing the larger
number on top. Then subtract these numbers. The answer will have
a 9 in the middle and the 2 outside numbers will equal 9.
Example:
321
- 123
198
