how many positive integers less than 100 have a remainder of 3 when divided by 13 ?
"we have to include 3 also . as 13 * 0 + 3 = 3 if somebody says to divide 3 by 13 , we will be telling we have 0 quotient and remainder as 3 . answer is e"
divide(factorial(subtract(add(const_4, 3), const_1)), multiply(factorial(3), factorial(subtract(const_4, const_1))))
