It is the place value of the first non-zero digit in the number.
Since 10 is a 2-digit number, it is necessary to find the numbers of combinations containing it and not containing it separately.There are 456 combinations containing 10 and 381 not containing it, making 837 in all.
Multiplying a 2-digit number by a 1-digit number involves multiplying the digits in the ones and tens place and then adding the products. Similarly, multiplying a 3-digit number by a 1-digit number follows the same principle, where you multiply the digits in the ones, tens, and hundreds place and then add the products. The main difference is that in the latter case, you are dealing with three sets of digits to multiply and add, whereas in the former, you only have two sets of digits.
