Is there a trick to figuring out factorials?
Not realy besides x! = x*(x-1)!. For some things there are approximations but these are only good for small ranges of values and complicated, generaly reserved for factorials of large numbers.
What are two ways in which whole numbers and decimal numbers are different?
Whole numbers are a proper subset of decimal numbers. All whole numbers are decimal numbers but not all decimal numbers are whole numbers.
When would one use factorials?
Factorials are a mathematics application used for combinations and permutations. The real world application of factorials are used to find the probability of certain things.
What is 42 as a quotient of two factorials?
For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42
How many numbers are in a decimal?
Any amount of numbers can be in a decimal.
Can the answers of factorials be decimals?
No. Factorials can only be placed on positive whole numbers or 0. For example, 0!, 1!, and 6! are all fine, but 2.5! and (-1)! are not. Since factorials can only be placed on whole numbers, that means you will only be multiplying whole numbers. 100! = 100 * 99 * 98 ... * 1; all those numbers are whole numbers, meaning your answer will be a whole number.
What is the factorial of 1?
Nothing. Factorials are only defined for whole numbers (non-negative integers).

What is the factorial value of -1?

What is the missing number in this sequence 1 2 6 24 -- 720?
120. The numbers are factorials: 1, 1x2, 1x2x3, etc.

For any pair of factorials, a! / a-1! = a. In this instance: 42! / 41! = 42
How many numbers are in a decimal?
Any amount of numbers can be in a decimal.
Do you have to shout factorials?
YES!
What are numbers expressed in the decimal system?
All real numbers can be represented in the decimal system. Complex numbers can be represented by a pair of numbers in the decimal system.
Why not all the decimal numbers can be written as rational numbers?
Decimal numbers that can be expressed as fractions are rational but decimal numbers that can't be expressed as factions are irrational
