what is the value of the underlined number? 170- the 0 is underlined, I know the place is the tens, thanks so much!

The VALUE of the underlined number is zero. The place is the ones.

It's not the tens place...didn't you read what I posted before?

The underlined # is also in the ones place just like 803 which you posted before.

Apologies for the confusion. The value of the underlined number in this case is zero. As you correctly mentioned, the place value of the underlined number is in the ones place. Therefore, the number 170 can be expressed as 100 + 7*10 + 0*1, where the zero does not contribute to the overall value.
