This is a serious website. people have questions that need to be answerd. If im mis understanding im sorry.

shadowfiend · Answer

I believe this is a legitimate question, vvnnhh.

anonymous · Answer

oh.. ahahaha

anonymous · Answer

6 factorial

n! = n*(n-1)!
0! = 1

so f.e:
5! = 5*4!
    = 5 * 4 * 3!
    = 5 * 4 * 3 * 2!
    = 5 * 4 * 3 * 2 * 1!
    = 5 * 4 * 3 * 2 * 1 * 0!
    = 5 * 4 * 3 * 2 * 1 * 1

myininaya · Answer

i know a short cut for multiplying binomials lol

coolme · Answer

what is that??

myininaya · Answer

look up the pascal's triangle

myininaya · Answer

1
                     1  1
     n=2        1  2  1
     n=3       1 3  3  1
     n=4      1 4 6 4  1
for (x+y)^n, the above are the coefficients
(x+y)^2=x^2+2xy+y^2   (make sure each terms has exponents add up to be 2)
(x+y)^3=x^3+3x^2y+3xy^2+y^3  (each term has exponents add up to be 3)
(x+y)^4=x^4+4x^3y+6x^2y^2+4xy^3+y^4  ( each term as exponents add up be 4)

myininaya · Answer

we can continue the triangle for n=5 and so on...
n=5:   coefficients are   1   5   10  10   5   1
(x+y)^5=x^5+5x^4y+10x^3y^2+10x^2y^3+5xy^4+y^5
