This lesson consists of showing you how to use the Sieve of Eratosthenes to find all prime numbers below a certain value. In this case, below 100. This is part of the Video Math Tutor series of FREE math self-tutorials. It is for students from 7th grade through college. It is useful also to those in home school and may be used by teachers and other tutors in their instruction or private tutoring. You may NOT charge others for this video or notes. The printable notes are available on my web site. The videos are useful for students needing help with their math classes or standardized tests (SAT, ACT, AIMS, etc.). Keystroke sequences are also provided, where applicable, for those with a TI-83 or TI-84 graphing calculator.
