Hexa Trex... Puzzle Rules

Object of the Puzzle

The object of the puzzle is to find the equation pathway that leads through ALL the tiles. 

For example, for this Hexa-Trex tile arrangement:

you would try to find this pathway:

Forming Equations

1. Two or three (or four or five etc.) digit numbers are made up of the individual tiles in the particular order as the equation is read. For example 5 x 5 = 2 5 is correct, but read backwards 5 2 = 5 x 5 is incorrect.

2. The equation must be continuous (no jumping over tiles or empty spaces).

3. Each tile can be used ONLY ONCE.*

4. Order of operations is followed. (Multiplication and division comes before addition and subtraction)

5. The tile “-” can be used as both a subtraction operation or a negative sign in front of a digit, making it a negative number.

* Note:  In previous versions of the Hexa-Trex puzzles, tiles could have been used more than once, with a clause that no immediate backtracking was allowed.  However, to keep things simple, in this collection of  puzzles (starting April 24, 2007), no tile is used more than once.
