    \[\frac{20!}{16!}= 20\times 19 \times 18\times 17\] the 16! cancels

    the 16! cancels out the rest from 16 to 1 so we are left with just 20.19.18.17

    ok so the term ! means you multiply all the numbers after that number 20*19*18*17*16 ---------------- 16 The sixteens cancle eachother out so you jsut have to multiply 20*19*18*17=116,280
