Math Problem Statement
Solution
Let's break down and answer each part of the image:
(1) What is your understanding of place value?
Place value refers to the value of a digit based on its position in a number. In our decimal system, each place represents a power of 10. From right to left, the positions are ones (10^0), tens (10^1), hundreds (10^2), thousands (10^3), and so on. For example, in the number 345, the place values of the digits 3, 4, and 5 are 300 (hundreds), 40 (tens), and 5 (ones), respectively.
(2) Write down the place value of the underlined digits:
- 54 _9_82: The underlined digit is 9, and it is in the hundreds place (10^2), so the place value is hundreds.
- 459 _2_34: The underlined digit is 2, and it is in the thousands place (10^3), so the place value is thousands.
(3) Write down the total value of the underlined digits:
- 54 _9_82: The digit 9 is in the hundreds place, so its value is 900.
- 459 _2_34: The digit 2 is in the thousands place, so its value is 2,000.

Here are 5 questions to further expand on this topic:
- How does the place value change when moving one place to the left in a number?
- How is the value of a digit affected by its place value?
- Can you explain how place value applies in decimal numbers (e.g., 3.456)?
- What happens to place values when multiplying or dividing a number by 10?
- How is place value used in large numbers like millions or billions?
Tip: Always start reading the place value from the rightmost digit, as this helps identify the ones, tens, and higher places step by step.
