Riddle me this, riddle me that. Why go the easy way when you can complicate? That is the idea behind this mathematical problems clock. Isn’t it more fun to have these conversations? “What time is it?” Oh, it’s 66 times square root of 198. “What time should we go out?” Let’s meet at 3*(PI – 0.14). If you know any math teacher or math lover then this is the best gift. This clock is also a good way to test if you are a geek.
