Evaluate the combination:

43C4

Combination Definition:

A unique order or arrangement

Combination Formula:

nCr =	n!
	r!(n - r)!

where n is the number of items
r is the unique arrangements.

Plug in n = 43 and r = 4

43C4 2	43!
	4!(43 - 4)!

Factorial Formula:

n! = n * (n - 1) * (n - 2) * .... * 2 * 1

Calculate the numerator n!:

n! = 43!

43! = 43 x 42 x 41 x 40 x 39 x 38 x 37 x 36 x 35 x 34 x 33 x 32 x 31 x 30 x 29 x 28 x 27 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

43! = 60,415,263,063,373,834,074,440,829,285,578,945,930,237,590,418,489,344

Calculate (n - r)!:

(n - r)! = (43 - 4)!

(43 - 4)! = 39!

39! = 39 x 38 x 37 x 36 x 35 x 34 x 33 x 32 x 31 x 30 x 29 x 28 x 27 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 16 x 15 x 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

39! = 20,397,882,081,197,441,587,828,472,941,238,084,160,318,341,120

Calculate r!:

r! = 4!

4! = 4 x 3 x 2 x 1

4! = 24

Calculate 43C4

43C4 =	60,415,263,063,373,834,074,440,829,285,578,945,930,237,590,418,489,344
	24 x 20,397,882,081,197,441,587,828,472,941,238,084,160,318,341,120

43C4 =	60,415,263,063,373,834,074,440,829,285,578,945,930,237,590,418,489,344
