What time is it?!

Put your number skills to the test with the mind-bending Graph Paper Pop Quiz Clock. Styled like old-school graph paper, this printed metal wall clock is emblazoned with tricky equations and scruffy workings-out, worthy of any mathematical whiz.

Thankfully, the answer to each baffling sum relates to where it sits on the clockface. So you’ll find minus-eight-equals-two-minus-X where you would normally find number ten. And so on. Talk about maths made easy!

A great gift for the wannabe number-cruncher in your life, the Graph Paper Pop Quiz Clock lets you tell time in the square root of a jiffy.

The maths problem for 9 is correct. 3 x (Pi -. 14). . 14 can be shown like this or as 0. 14. Pi - 0. 14 = 3, so therefore 3(3) = 9.
John Cheshire, Suffolk - 5th November 2011

Pi = 3. 14159265... pi-3. 14= 3. 00159265 3x(pi-3. 14)= 9. 00477795 o'clock??? 52- x^2 + x = 10 (-x+7)(x+6) = 0 x = 7 or -6 -6 o'clock :P despite this an awesome clock... and will be ordered next paycheck.

Firebox says: eh? we are just about at our maths limit with 102,413 - 102,412, that's 1 right?

Pretty good clock because you can put your own funny maths equations on instead of the ones in the advert since a few of them are incorrect (if you're going to be pedantic).
