Hi Mayflow

Does the fact that if they next meet at x degrees past 12, the minute hand travels 360+x degrees and the hour hand travels x degrees.

Well that twisted my mind around, and was initially what I thought too.  A thing about this though is that the clock only goes 360 degrees, and the minute hand starts at 1 o'clock again at zero degrees.

So, I thought (instead of the minute hand traveling at 360+x degrees)  then of the ratio of an  hour hand traveling at 360-x degrees compared to the 360 degrees of the hour hand.
But Stefy, I think you are the right trail.

Consider that the minute and hour hands of a clock are superimposed at 12 o'clock. Precisely when again will they meet hands again "be superimposed?".

Also when in each 12 hours will they be superimposed, and how many times in 12 or 24 hours will they superimpose?

Keep in mind that the minute hand travels at 360 degrees per minute and the hour hand travels 60 times slower.

The thing I like most is the formalism and rigour.

Referring to math? If so, you have spotted a problem of mine. In school I could get the correct answers (usually) but I often could not explain how I got them. I have a job now, (RF calibration technician) and the other day an Engineer presented me with a math question he said any 7th grader should be able to answer. I really worked on it, and it took a long time and I showed him how I got the answer, and he said I had just come up with a gimmick and could not explain a certain ratio I had figured out. However, I did later come up with what I think is a reasonable explanation.

Where is the best place to put an algebra question on the forum? I will present the question there. There is actually a little twist to the plot (which I have not worked on yet) - but it would be best if we can mutually agree to the correct answer to the first question first - of course I am sure there will be more than one way to go about answering the question.

Hi;

I am afraid Yoda is incorrect there, success is an illusion.

Math is a language made up by the mind of man, but math cannot explain the minds that made it up.

I think you need philosophy for that, I just always wanted to know how many pears, apples and peaches can you distribute to 5 different kids.

Depends on how many fruits you have divided by 5, and if you want to distribute them equally.

Besides I am not Yoda. Isn't your Avatar of Yoda?

Hi;

Welcome to the forum.

I have high school math and no more,

According to Zeilberger that is all you need. I have been struggling to get that much all my life.

Struggle you do, success you will find, Yoda. It is only the good heart that becomes the champion. Math is a language made up by the mind of man, but math cannot explain the minds that made it up.

Hi. Can't you have an easier to type name? Do you or would you like to have a nickname?

Thanks. Well welcome to ... er well, my being on the forum? The fun thing about math to me (and mind you, most of you will likely know a lot more math than I do) is that it is about how things (numbers and units I guess) relate to one another.

What does math mean to any and all of you, and what use is it do you think?

I have high school math and no more, but I do think math is fun and life is fun, so I hope to have some fun here and maybe learn a thing or two along the way, so I dip my toes into the waters here - no biting! :-)
