Divisibility Rules and Examples

The video tutorial from Moomoomath and Science explains how to determine if a number is divisible by six. It introduces the concept by stating that a number is divisible by six if it is divisible by both two and three. The video then details the divisibility rules for two and three: a number is divisible by two if it ends in 0 or an even number, and divisible by three if the sum of its digits is divisible by three. Two examples are provided: 252 and 4470, both of which are shown to be divisible by six using these rules. The video concludes with a call to action to subscribe for more math and science content.
