Which number represents the smallest amount among the following options: 3899, 629, 89001, 9867?

Explanation:
The key idea is that fewer digits mean a smaller number, and if two numbers have the same number of digits, you compare from the leftmost digit to the right. Here, 629 has three digits, while the others have four or five. Any three-digit number is smaller than any four- or five-digit number, so 629 is smaller than 3899, 9867, and 89001. Since there are no other three-digit numbers to compare, 629 is the smallest amount. For perspective, any four-digit number is at least 1000, which is already bigger than 629, and a five-digit number is even larger.
