Mathematical Expressions Clock 65 66
Mathematically Awesome Purchase I have seen many mathematical expression clocks on the internet, but this one puts you in math classroom with the green background and expressions that give viewers some challenges. I have had varying comments from colleagues in the office and the comments like, "what kind of clock is this?" gives me satisfaction as I explain to them that every expression matches the number it represents. This is worth what I paid for it.---DDCP June 18, 2013
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
