how many positive integers less than 300 are there such that they are multiples of 17 or multiples of 16 ?
"300 / 17 = 17 ( plus remainder ) so there are 17 multiples of 17 300 / 16 = 18 ( plus remainder ) so there are 18 multiples of 16 we need to subtract 1 because 17 * 16 is a multiple of both so it was counted twice . the total is 17 + 18 - 1 = 34 the answer is d ."
divide(factorial(subtract(add(const_4, 17), const_1)), multiply(factorial(17), factorial(subtract(const_4, const_1))))
