*************************************** MathMagic Cycle 18: Level 10-12 Regular *************************************** Using the numbers 1 9 9 2 in a "locked" position, can you develop a 31 day calendar for the month of October? You can use addition (+), subtraction (-), multiplication (*), division (/) exponents (^) factorial (!) square root (sqrt) and, naturally, parenthesis ( ). Example: Friday the 13th could be: (1+sqrt(9))!-9-2 (Scary, isn't it?) (Notice that the numbers appear in the "locked" sequence) **************************************** MathMagic Cycle 18: Level 10-12 Advanced **************************************** What 6 digit number, with 6 different digits, when multiplied by all integers up to 6, circulates its digits through all 6 possible positions, as follows: ABCDEF * 1 = ABCDEF ABCDEF * 3 = BCDEFA ABCDEF * 2 = CDEFAB ABCDEF * 6 = DEFABC ABCDEF * 4 = EFABCD ABCDEF * 5 = FABCDE ********* Good luck MrH
