how many zeros does 100 ! end with ?
"according to above 100 ! has 100 / 5 + 100 / 25 = 20 + 4 = 24 trailing zeros . answer : b ."
add(add(divide(100, add(const_4, const_1)), divide(subtract(100, add(const_4, const_1)), power(add(const_4, const_1), const_2))), divide(subtract(100, add(const_4, const_1)), power(add(const_4, const_1), const_3)))
