how many integers between 100 and 160 , inclusive , can not be evenly divided by 3 nor 5 ?
"the total numbers between 100 and 160 , inclusive , is 61 . 3 * 34 = 102 and 3 * 53 = 159 so the number of multiples of 3 is 20 . 5 * 20 = 100 and 5 * 32 = 160 so the number of multiples of 5 is 13 . however , the multiples of 15 have been counted twice . 15 * 7 = 105 and 15 * 10 = 150 so the number of multiples of 15 is 4 . thus the total number is 61 - 20 - 13 + 4 = 32 . the answer is a ."
subtract(160, add(add(multiply(const_2, const_100), multiply(add(const_3, const_4), const_10)), const_2))
