When multiplying 6 x 7, Tarkib Adadi allows distributive property:

This is the "building up" process. Given two or more parts, what is the whole?

In classrooms, these are often taught using Number Bonds (numeric diagrams showing a circle for the whole and branches for the parts).


Understanding that a ten is composed of ten ones is a large-scale tarkib adadi. Similarly, understanding that 35 is composed of 3 tens and 5 ones requires the same cognitive skill of seeing a whole number as a collection of parts.
