Expanded form of a number shows the value of each digit according to place. If a number is written as 800 + 70 + 2, which digit is in the tens place?

• A. 8
• B. 7
• C. 0
• D. 2

Answer: (B)

Place value is what this item is testing. Expanded form shows the value of each digit by its position: hundreds, tens, then ones. In 800 + 70 + 2, the 800 represents eight in the hundreds place, the 70 represents seven in the tens place, and the 2 represents two in the ones place. The digit in the tens place is the one that makes up the 70, which is 7. So the tens-place digit is 7.
