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

**Steve**, Saturday, November 3, 2012 at 12:10pmHmmm. 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.

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 !!! :)
