Mathematical Expressions Clock 64 65
Prompt replacement The first clock was defective. The company immediately sent a replacement. They also provided a return postage label through email. June 16, 2013
Great! I bought this as a birthday gift for my math teaching husband, and he loves it! It has more complicated math than other clocks similar to this that I've seen, and that makes him (not so much his students! =D) very happy! June 10, 2013
What time is it? Bought this for my son who is an engineer. Only he could verify that the formulas were correct. Great conversation piece and clock. June 7, 2013
Great gift for NASA nut There are several "math clocks" on the market, but this one stole my heart - I only knew how to solve ONE of the problems, but was glad to hear my NASA bro in law was able to figure out 7 out of 12. Fun and challenging! June 4, 2013
