FAQ

Everything you need to know about this question

Why do we start counting from the right side?

+

In our number system, the rightmost position is always the units place. This stays consistent no matter how many digits the number has - whether it's 9 or 85,119!

What if there are commas in the number?

+

Commas just help us read large numbers easier! Ignore the commas when counting place values. In 85,119, just count: 9(units), 1(tens), 1(hundreds), 5(thousands), 8(ten-thousands).

How can I remember the place value names?

+

Use this pattern: units, tens, hundreds, thousands, ten-thousands. Each place is 10 times bigger than the one to its right. Practice with smaller numbers first!

What if the same digit appears twice?

+

Each position has its own place value! In 85,119, there are two 1's: one in the tens place and one in the hundreds place. The question asks about the digit 9, which appears only once.

Is there a trick to avoid mistakes?

+

Yes! Write the place value names under each digit: T-Th | Th | H | T | U. Then match each digit to its place. For 85,119: 8=ten-thousands, 5=thousands, 1=hundreds, 1=tens, 9=units.
