what is the 10 th digit of ( 5 ! * 4 ! * 4 ! - 5 ! * 4 ! * 3 ! ) / 2880 ?
"( 5 ! * 4 ! * 4 ! - 5 ! * 4 ! * 3 ! ) / 2880 ? = 5 ! * 4 ! ( 4 ! - 3 ! ) / 4 ! * 5 ! = 4 ! - 3 ! = 18 sum of digits = 1 answer b"
floor(divide(divide(add(multiply(factorial(5), factorial(4)), multiply(factorial(const_4.0), factorial(const_3.0))), 4), 10))
