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 number sequence 3 4 6 9 13?
There are infinitely many rules based on polynomials of order 5 such that the first five numbers are as listed in the question. There are also non-polynomial solutions. Short of reading the mind of the person who posed the question, there is no way of determining which of the infinitely many solutions is the "correct" one.
The simplest answer, based on a polynomial of order 2 (a quadratic) is
U(n) = (n^2 - n + 6)/2 for n = 1, 2, 3, ...
I will be glad to give you a complex number. (i^i)^i is i raised to the i power and
raised to the i power again. This is not the same as i^3 which is -i but computes to .947 + .321i
If you get a whole number while doing square roots what would the answer be rational or irrational?
A rational number is a number that can be expressed as the division of two integers, while the divisor is not zero. An irrational number is any number that is not rational.
Whole numbers are rational, because the divisor is 1. It has nothing to do with square roots.

What are all the prime numbers from 100-300?
101 103 107 109 113 127 131 137 139 149 151 157 163 167 173 179 181 191 193 197 199 211 223 227 229 233 239 241 251 257 263 269 271 277 281 283 293.
What number is prime but even?
A prime number is any number that only has one and itself as factors. By definition even numbers have a factor of two. Therefore the one even number that is also prime is the number 2.
Why are there 500 prime numbers?
The question does not make sense. There are not 500 prime numbers but infinitely many!
How many prime factorizations does every number have?
Every prime number has exactly 2 factors, 1 and the number itself.
Would a negative minus a negative automatically become plus?
No, for example. -8- -3 = -5, because it's as if you added 3 to negative 8, which brings you to -5.
What are the factors of 150 and 300?
Start with the prime factorization of 300:
300 = 2 X 150 = 2 X 3 X 50 = 2 X 3 X 5 X 10 = 2 X 3 X 5 X 2 X 5 = 22 X 3 X 52.
Using the result from above, we can see that the prime factorization of 150 is:
3 X 5 X 2 X 5 = 2 X 3 X 52.
To find every factor for these two numbers, we need to find every possible product, omitting repeated products, of all of the numbers of their respective prime factorizations.
Since 150 is a factor of 300, as shown above, we'll start there. That will give us the set of these two numbers' common factors.
2 X 3, 2 X 5, 2 X 3 X 5, 2 X 5 X 5, 3 X 5, 3 X 5 X 5, and 5 X 5 are all factors, as are 1, 150, and the prime factors 2, 3, and 5.
Thus, the set of all factors of 150 is:
{1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150}.
As stated before, these are all going to be factors of 300 as well, however 300 has some additional factors, namely:
2 X 2, 2 X 2 X 3, 2 X 2 X 5, 2 X 2 X 3 X 5, 2 X 2 X 5 X 5, and itself.
Thus, the set of all factors of 300 is:
{1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 25, 30, 50, 60, 75, 100, 150, 300}.
Can Planck's constant is zero?
No. It is a very small number (approximately 6.626 × 10-34 joule-second) but that is NOT zero
How do you turn 7.016 into a mixed number?
mixed means whole number and fraction
7.016 means 7 and 16 in the thousandths place
So, 7.016 = 7 16/1000
In lowest terms, 7 2/125
