Numbers
Numbers are our way to quantify, label, and organize the world around us in a logical manner. However, the systems used to obtain this goal differ geographically, historically, and by relative utility. All questions pertaining to numbers, including historic labeling systems, bases of numerical systems, constants, and the various ways they're grouped together, should be placed into this category.

Are all deficint numbers odd numbers?
No. From Wikipedia: "The first few deficient numbers are: 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, 13, 14, 15, 16, 17, 19, 21, 22, 23, 25, 26, 27, ..." As you can see, the list includes both even and odd numbers. For example, all powers of two are deficient.
How do you produce an irrational number with no zeros in it?
The number sqrt(2) has no zeros in it, only the digit 2!
If you mean that the decimal representation has no 2 in it, you could create an infinite decimal fraction by selecting, at random, a digit from the set {1,2,3,...,9}. Clearly it cannot have a 0 in it and, thanks to the randomness, it will be irrational.
What is a number that is not a square number?
Any number which cannot be represented by that number of beads/dots/other_symbols_or_objects arranged in a square, for example 2, 3, 5, 6, 7, 8.
Square numbers are thise that can be represented by that number of beads/dots/stars/other_symbols_or_objects arranged in a square:
* = 1^2 = 1
** = 2^2 = 4
**
***
*** = 3^2 = 9
***
etc.

How to write thirty one hundred thousand in number
Nowadays we think that the equivalent of 9 in Roman numerals is only IX whereas in fact IX is an abridged version of VIIII in ancient Roman numerals thus facilitating the conversion and calculations of the given Hindu-Arabic numerals into Roman numerals in several ways as follows:-
MDCCLXVII+VIIII = MDCCLXXVI => 1767+9 = 1776
MDCCLXVII+IX = MDCCLXXVI => 1767+(-1+10) = 1776
MDCCLXVII-VIIII = MDCCLVIII => 1767-9 = 1758
MDCCLXVII-IX = MDCCLVIII => 1767-(-1+10) = 1758
Note that in mathematics that -(-1+10) is equivalent to +1-10 and so -(-I+X) is equivalent to -VIIII
Is there a number that's rational and irrational?
No - the sets of rational and irrational numbers have no intersection.
A rational number is any Real number that CAN be represented as a ratio of two integers where the denominator is not zero.
An Irrational number is any Real number the CANNOT be represented as a ration of two integers.
