The first three-digit number is 100. It is the smallest integer that has three digits, starting from 1 and followed by two zeros. Numbers below 100, such as 99, are considered two-digit numbers.

It does not have to be. 864/2 = 432. The first digit of the quotient is not in the tens place.
Multiply the three-digit number by the one's digit, or last digit, of the two-digit number. That is your first part. Now multiply by the second-to-last digit, or ten's digit, and multiply the result by 10. That is your second part. Add the two parts and that is your answer.

The smallest three-digit number divisible by the first three prime numbers (2, 3, and 5) and the first three composite numbers (4, 6, and 8) is 120.
The first three-digit number is 100. It is the smallest integer that has three digits, starting from 1 and followed by two zeros. Numbers below 100, such as 99, are considered two-digit numbers.
A three digit number is any counting number between 100 and 999 (inclusive). It is made up of three digits, the first of which cannot be 0.
There are 10 digits, but for a three digit number the first number cannot be a 0. Thus: there is a choice of 9 digits for the first (and last digit which must be the same), with 10 choices of digit for the second (middle) digit, making 9 × 10 = 90 such palindromic numbers.
