math clock

 

math "pop quiz" clock
A day's worth of math problems... OK, maybe a year's worth for a few of us. Some of them are much easier than others, and you can probably guess the result of the equations without actually remembering basic math... but it kind of makes you think!

requires 1 AA battery (not included)
