How can you find the ones digit for the standard form of the number?

In elementary school, we teach it as an "HTO" chart.
H=Hundreds, T=Tens, O=Ones. The HTO shows the order in which they appear. The ones place
is all the way to the right, tens in the middle, hundreds all the way to the left. Of
course, place value extends far beyond just ones, tens, and hundreds...but I thought
this example might at least help you with remembering basic place value a.k.a. the ones
place. :)
