Показать описание

You can learn about a number by just looking at its last digit. In this video, we uncover why just the last digit can determine the divisibility by 2, 5 and 10. This same line of reasoning can be used to determine the divisibility by some other numbers like 4 and 8.

Basically,
The divisibility rule for 2:
If the last digit of a given number is an even digit.

The divisibility rule for 5:
If the last digit of a given number ends with 5, or 0.

The divisibility rule for 10:
If the last digit of a given number ends with 0.
