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.

How many decillions are in 1 googol?
In researching the answer, we found the following definitions on the www :
1 decillion = 1033
1 googol = 10100
So the number of decillion in 1 googol is
10100 / 1033 = 10(100-33) = 1067
We couldn't find a name for 1067. Apparently it doesn't come up very often.

A prime number is any number that only has one and itself as factors. Therefore, to tell if a number is prime simply find it's factors. If it has more than two factors than it is not a prime number.
Yes, but there is only one of them. A prime number is any number that only has only one and itself as factors. By definition even numbers have a factor of two. Therefore the only even number that is prime is the number 2.
No. 2 is a real number, whole number, and rational number.

What integer divided by negative 3 equals the sum of positive 12 and negative 20?
Start by setting up an equation. Use x for the integer. The equation would be:
x/-3=12+-20
Find the sum of 12 and -20 which is -8. Therefore the equation would now be:
x/-3=-8
Multiply -8 by -3 which equals 24.
Therefore x=24
Plug it back into the equation to check that it works:
24/-3=12+-20
24/-3=-8
-8=-8
Thefore 24 is the integer that when divided by -3 it equals the sum of 12 and -20.
