Eighth grade algebra extra worksheet to help students learn to think. Question: What is the highest number possible with 3 digits? The teacher said the answer is not 999 and that the question did not say "3-digit number." My answer then is 9 to the 99th power (written mathematically of course) as this uses "3 digits" and is obviously a huge number. Is this correct? Thank you.


Hi Liz.

You're definitely thinking along the right track.

You correctly determined that 999 is larger than 999. Now how can you use two nines to make a number larger than 99?
