ten thousand value chart
Answer:

Explanation:
A place value chart is diagram that helps us to find and compare the place value of the digits in numbers through millions. The place value of a digit in the place value chart increases by ten times as we shift to the left and decreases by ten times as we shift to the right.
For example for ten thousand place value chart where we write 10,000 as 10 in thousands place, 0 in hundreds place, 0 in tens place and 0 in ones place as shown above.
