Question 1096567
<br>(1) Find the sum A of all the integers from 1 to 100.
(2) Find the sum B of all the integers from 1 to 100 that are divisible by 3.
(3) Find the sum C of all the integers from 1 to 100 that are divisible by 5.
(4) Subtract B and C from A.<br>
At this point, the numbers that are divisible by 15 have been subtracted twice, so we need to add them back in.<br>
(5) Find the sum D of all the integers from 1 to 100 that are divisible by 15.<br>
The number of integers from 1 to 100 not divisible by either 3 or 5 is
A - (B+C) + D.<br>
I will let you do the calculations....  You should come up with answer choice D, 2632.
