I'm assuming you're referring to the nCr combination formula

n C r = (n!)/(r!(n-r)!)

12 C 6 = (12!)/(6!*(12-6)!)

12 C 6 = (12!)/(6!*6!)

12 C 6 = (12*11*10*9*8*7*6!)/(6!*6!)

12 C 6 = (12*11*10*9*8*7)/(6!)

12 C 6 = (12*11*10*9*8*7)/(6*5*4*3*2*1)

12 C 6 = (665280)/(720)

12 C 6 = 924

Answer: 924
