Explaining the division of a unit length into 10 equal parts.
When exact measures are required, we can divide a unit length into equal parts. Each smaller part represents one-tenth () of a unit.

Sonu's arm measurement addition example.
Sonu is measuring his arm. His lower arm measures units, and his upper arm measures units. What is the total length of his arm?
Shylaja's finger measurement subtraction.
The length of Shylaja’s hand is units, and her palm is units. To find the length of her middle finger, we must subtract the palm from the total hand length. We cannot remove one-tenths from one-tenths, so we split a unit from to get one-tenths. The hand length now becomes units and one-tenths. Now, we subtract the whole units: . Next, we subtract the fractional parts: one-tenths minus one-tenths equals one-tenths. This gives a final finger length of units.
