Math History
Far more interesting than one might first expect, the history of mathematics is filled with bitter rivalries, political machinations, and incredible innovations by some of the most amazing minds in history. Post all questions concerning individual mathematicians, the development of mathematical theories, and the sociological impact that resulted into this category.

What kind of angle is always the same distance apart?
An angle has no distance and so there is no angle which is the same distance apart.
What mathematical disaster does the derivative avoid?
The derivative was introduced to clarify the concept of "slope", specifically in the case of curves. It was not created specifically to avoid a "mathematical disaster", but it was possible to formalize the definition of slope (derivative) in such a way that concepts that are not very precise, such as "infinitely small", are avoided. This has been done by defining the derivative in terms of limits.
What are the numbers that have an odd factor?
Every integer number has an odd factor unless it doesn't, i.e. unless it only has even factors. An even factor can have an odd factor, unless it has only factors 2 (since it is the only even prime).
So, a number has an odd factor if it is unequal to a power of 2.
Note that 0 is not a power of 2 and has all odd factors . . .
What is the multiples of 9 8 4?
They are members of the infinite set of numbers of the form 72*k where k is an integer. Since the set is infinite, it is not possible to list them.
What is the contribution of Rene descartes?

When were luminous signs first used?
At the end of the nineteenth century, luminous signs were a new phenomenon.
How is Alexander grothendieck most famous idea used in the 5th grade?
Pupils in different countries learn different parts of mathematics so, without knowing which country the question refers to, it is not possible to be sure of the answer. However, I suggest that it is coordinate geometry, also known as algebraic geometry or analytical geometry.
Are there number systems when there is no zero?
Yes, older number systems tended not to use the zero. But that makes those number systems rather limited.
Who discovered the symbol in empty set?
Andre Weil first used it in 1939 and got the idea from a letter in the Danish and Norwegian alphabet.
Yes. You might even be able to find that information here, if you could be a bit more specific.
Is the ratio 4.7 equal to 20.20?
A ratio is a relation between two numbers, so 4.7 by itself is not a ration.
Why is there no Egyptian symbol for zero?
Like many systems, you either have some of something, or you don't. If you do, you use a number for it. If not, no number is required. What is the point of saying "Hi fred, I own 0 Rolls Royces?"
