Thanks Ms. Sue for givig me the anser of 11,211 for my son's math problem(I have 10 thousands, 11 tens, 12 hundreds, and 0 ones. What number am I?) However, I am still confused and need a little more clarification? I understand place value order.

Question

Thanks Ms. Sue for givig me the anser of 11,211 for my son's math problem(I have 10 thousands, 11 tens, 12 hundreds, and 0 ones. What number am I?) However, I am still confused and need a little more clarification? I understand place value order.

If there are 0 ones, why is there a 1 in the ones place? Isn't that 1 ten which is 10 not 11 (1 ten plus 1 )?
If there are 11 tens, why is there a 1 in the tens place? Where did the remaining value of the tens "go"?

Thank you again

Answer 1

Hmmm. I get

10000 + 110 + 1200 + 0 = 11310

as for the 1 in the 10's place, the place can only hold a single digit. 11 10's = 110, so a carry has to go over to the hundreds place.

Must have been a typo. Ms Sue is usually quite reliable, but at least you checked your answer. Sounds like you knew how to do it anyway.

Answer 2

Thank you Steve.

Your answer is the same that I calculated before I posted my question. My son's teacher gave them the incorrect answer. I am a teacher as well & I wanted another opinion.

Thanks !!! :)

Answer 3

You're welcome! I'm glad I could help clarify the answer for you. Let's break down the number 11,211 to better understand its place value.

In the given number, "10 thousands, 11 tens, 12 hundreds, and 0 ones," we can visualize it as:

10,000 | 1,000 | 100 | 10 | 1
1 1 2 1 0

Starting from the rightmost digit (ones place), we see there is a 0, which means there are no ones in the number. Therefore, the digit in the ones place is indeed 0.

Moving on to the tens place, we have 11 tens. Each group of ten is equal to 10. So, if we have 11 tens, we have a total of 11 times 10, which gives us 110. That's why there is a 1 in the tens place – it represents 1 group of ten. The remaining value of the tens (1) is represented in the hundreds place, as there were 12 hundreds. So, you are correct, the remaining value of the tens did not disappear; it was carried over to the hundreds place.

To summarize, in the number 11,211, the digit in the ones place is 0 because there are no ones. The digit in the tens place is 1 because there are 11 tens, which is equivalent to 110. The remaining value of the tens (1) carries over to the hundreds place.
