Odd or Even

Even numbers have a 0, 2, 4, 6, or 8 in the ones place.
Odd numbers have a 1, 3, 5, 7, or 9 in the ones place.

37847

There is a 7 in the ones place: 37847
Odd numbers have a 1, 3, 5, 7, or 9 in the ones place.
So the number 37847 is odd.

Example 2:

There is an 8 in the ones place: 29588
Even numbers have a 0, 2, 4, 6, or 8 in the ones place.
So the number 29588 is even.
