- I thought this was funny so I called my wife (a math teacher) to take a look: "What is it -6 or 7 o'clock here? And pi -
*.14*?!*There's so much wrong here I can't even look at it*.".I suppose that's one difference between engineering and pure math in that sometimes*close*is good enough. Still, pretty funny to me. Harold,

It is a clock dial, so it you do the calculations rounding to the nearest integer, you will get the numerals for the hours on the dial. Clocks do not have decimals on the numerals.

*int[3*(pi-0.14)]*=**9**Regarding the equations:

If

*52-X^2+X = 10*then X =**7**[52-(7^2)-7] = 10On the expression if

*-8=2-X*then X =**10**etc.

- I do get it. Did I not say I find it funny? My point was that the clock would be fine in an engineering dept but would just not pass scrutiny for a mathematician (like my wife). It's like the difference between asking a math person or physics person what 1/infinity equals. After the physicist tells you it's 0 the mathematician will leave the room in disgust.52 - X^2 - X = 10X^2 - X - 42 = 0(-1 +/- (1 - (4)(1)(-42))^1/2) / ((2)(1))= 7 or -6 (rounding to the nearest integer)
"...don't they know you have to choose the logical answer?" In a word: No. The answer is the answer if you have ever experienced it or not.

I had a friend growing up that had a kitchen clock with the numbers in reverse order and it ran backwards. Only one like I have actually seen. Makes me believe there are other clocks with unexpected numbering that I would never anticipate. The key is framing the question properly. If X can only be greater than 0 to satasfy the design requirements then it must be stated at the start.

We happen to enjoy antagonizing each other with details like that. Ask for

*exactly*what you want or you might be surprised at what you get!I had a friend growing up that had a kitchen clock with the numbers in reverse order and it ran backwards.

I have a friend that collects watches and he has one that the numbers are not in the right place but it keeps the right time. The hour hand will jump to the right location. Like the 3 is in the normal 11 spot but when it is 3 o'clock at first look it looks like its says 11. Neatest things I have ever seen to bad I can't afford to buy one.

Remember, globalization means people of all nationalities need to be able to figure it out. I'll work on it some more tonight, but I would suggest "B" for 11 o'clock, and "111" for seven. (Hint: Most the computer/EE people should be able to figure it out...)

Perhaps less numbers, more Greek symbols.
