Answer :
The problem is the number 913,256. If we work from 6 over, we know that
the #’s are in the following places: 6 is in the ones, 5 is in the tens, 2 is
in the hundreds, 3 is in the thousands, 1 is in the ten thousands, and lastly,
9 is in the hundred thousand spot.
Kids are taught to group these numbers. Therefore, the one spot, ten
spot, and hundred spot are called Ones period. On the other hand, the
thousands, ten thousand, and hundred thousand are grouped in the Thousands
Period. A period is three digits’ each group in a number.
