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.

What is so hard about mixed numbers?
Well, I mean, if they're mixed, people might think they're harder than they really are, which causes panic in your brain cells, which might have an effect on the mixed numbers. It's basically like if you have a test and it's counting for 45% of your grade, then you freak out and think it's hard, but really if you study enough, it will be quite easy. It's just a weird effect on your brain cells, but for others it's just that they didn't sleep well or didn't study because they thought they were so cool.
Is 4500 a prime or composite number?
A prime number has only 2 factors which are 1 and itself. Composite numbers are everything else except 1 and 0. 1 and 0 are neither prime, nor composite. 4500 is composite.
Is 293 and 760 composite numbers?
293 is a prime number
As 760 is ending by 0 it can be divided by 5, thus it's not a prime number
760 = 23 x 5 x 19
What is the mixed number of a fraction 11 46?
The absolute value of 11/46 is less than 1 and so there cannot be a mixed fraction.
What 2 numbers multiply to 100 and subtraction to 5?
1. x * y = 100
2. x - y = 5
y = x - 5
3. x * x - 5 = 100
x2 -5x = 100
x2 - 5x - 100 = 0
Using the quadratic formula this solves to:
x = 12.808 (to 3 decimal places) and - 7.808 (accurate to 3 decimal places).
As y = x - 5 then
y = 12.808 - 5 = 7.808
and
y = -7.808 - 5 = -12.808
Thus the answers are 12.808 and 7.808 or -7.808 and - 12.808 (accurate only to 3 decimal places - for increased accuracy use the quadratic formula and round the numbers to more decimal places).
What number below thirty have products of three prime numbers?
2 x 2 x 2 = 8
2 x 2 x 3 = 12
2 x 3 x 3 = 18
2 x 2 x 5 = 20
3 x 3 x 3 = 27
2 x 2 x 7 = 28
A binary (not binari!) number does nothing. It is a number and is not capable of any action.
