An even number is a whole number that is divisible by 2 without leaving a remainder. In other words, if a number can be divided by 2 and the result is a whole number, then it is an even number.
Now, let's consider the number DBD. Since D, B, and D are digits, DBD represents a three-digit number where D is in the units place, B is in the tens place, and D is in the hundreds place.
For DBD to be an even number, the digit in the units place (D) must be even. This is because any number ending in an even digit is itself even.
Therefore, if the digit D is even, then DBD is guaranteed to be an even number, regardless of the values of B and the other D.
So, to determine if DBD is an even number, we only need to check if the digit in the units place (D) is even. If it is, then DBD is an even number. If it is odd, then DBD is odd.
