Multiples are numbers in a times table. The multiples of 2 always end in 2, 4, 6, 8, or 0, while multiples of 5 always end in 5 or 0. Knowing whether a number is a multiple of 2 or 5 can be determined by looking at the last digit.
1. Multiples
Multiples are really just extended times tables.
The multiples of 2 are all the numbers in the 2 times table, such as 2, 4, 6, 8, 10
and so on.
Multiples of 2 always end with a 2, 4, 6, 8 or 0. You can tell 2286, for example, is
a multiple of 2 because it ends with a 6.
The multiples of 5 are all the numbers in the 5 times table, such as 5, 10, 15, 20, 25
and so on.
Multiples of 5 always end with a 5 or a 0. You can tell 465, for example, is a
multiple of 5 because it ends with a 5.
