A digit's value is the digit multiplied by the value of its place. Place values are the number of the base raised to the nth power, where n is the number of other digits between a given digit and the radix point.
The units represent ones, rods represent tens, flats represent hundreds, and the cube represents thousands. Their relationship in size makes them a valuable part of the exploration in number concepts. Students are able to physically represent place value in the operations of addition, subtraction, multiplication, and division.

[11] A much later advance was the development of the idea that 0 can be considered as a number, with its own numeral.
"A student might come up to the front of the room to work through the first problem, sharing his or her thinking out loud. The teacher might question students and help them formulate their thinking into general guidelines for estimation, such as "start by estimating the sum of the highest place-value numbers".
