This document provides an overview of divisibility tests for numbers 2 through 11. It explains the tests to check divisibility by each number without performing long division. For each number, it gives the method, such as checking the last digit for 2 and 5, summing the digits for 3 and 9, checking the last two digits for 4, last three digits for 8, separating odd and even digits for 11.
