Can't tell the difference between + and divide on a lot of puzzles! Make it clearer!!
PD, Oxford,
My husband and I love working these puzzles out together, looking forward to the book!
Sharyn, London,
Why not just use the / for division and just put a space between the symbols? So for the first puzzle on March 22 it would be
+ - / x

Please make the symbols more legible!!

The problem I have is to read the math symbols in the puzzles. The printed version has very unclear symbols. If you copy into WORD to blow up the magnification they become even more blurred. There appears to be no way of being sure, particularly, of what is plus and what is divide. The puzzles need to be larger and clearer.
Is there a another way of magnifying the KenKen to make it clearer?

Ref "Mike" previous - OK, so some of the symbols that look like "2+" are actually "2 division-sign". On my screen (which is a reasonably good one) it's impossible to distinguish between the two symbols. Please can you show the puzzles at higher resolution? Same comment goes for clue numbers in the Mephisto crossword.

Your instructions don't mentions that '-' should be read as absolute difference, not subtraction, and that you should substitute a similarly defined commutative operation for division where you see '÷'. Unless all operations are commutative, you won't be able to fill in the top right hand corner of puzzle no 8.
