The Pop Quiz Clock gives you equations instead of numerals, angst instead of answers, heartburn because of missed trains. Yeah of course it’s only a bit of fun, especially since everyone knows that 198 divided by 66 equals…um…  Around $40.00 or so.

 Don’ Worry! We have plenty of time. It is only ten past -8=2-X… The 30 cm big face of the clock has a cool graph paper print, where upon a series of equations are scribbled instead of the traditional display of numbers.
