What number cannot be divided by 2 without a remainder?

Answer 1

Integers that can be divided by 2 without a remainder are called "even".

Integers that, when divide by 2, have a remainder of 1, are called "odd".

In the decimal system, even numbers end with 0, 2, 4, 6, or 8. Numbers that end with 1, 3, 5, 7, or 9 are odd.
