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.
