{{Numberblocks_Character|title1=Compound Numberblocks|debut=[[I Can Count to Twenty]]|image1=FirstCompoundAppearance.jpg|caption-image1=An example of a Compound Numberblock, this is a compound version of [[Twenty-One]].}}

Sometimes, when two or more [[Numberblocks (characters)|Numberblocks]] of different place value join together and make a new number, they do not become a single entity and instead take the form of a conjoined version of both Numberblocks. These are colloquially known as '''Compound Numberblocks'''. They first appeared in [[I Can Count to Twenty]] in the form of [[Twenty-One]] and have become recurring characters since then.

Compound Numberblocks are based on the math topic called expanded form, where numbers can be broken into addition expressions where each addend is one of its place values (for example: 67 is [[Sixty|60]] + [[Seven (character)|7]]). When they are formed, they do not have a fully defined personality. Once they do develop a personality (usually through the means of learning their properties), they “figure themselves out” and permanently combine into a singular entity.

== Trivia ==

* The concept of the Compound Numberblocks originates from production of [[The Big One]]. Originally, every Numberblock beyond [[Twenty (character)|Twenty]] (with the exceptions of multiples of 10) was to appear in their “figured-out” form. This idea was decided against as each of them would have only a few seconds of screentime at most, and the Compound Numberblocks were created as a compromise. Though compounds debuted earlier in [[I Can Count to Twenty]], this episode and [[Twenty-One and On]] are the first episodes where they were properly established.
* The fact that Twenty-One in I Can Count to Twenty appears as Twenty and One conjoined reflects how the Alphablocks form digraphs and trigraphs (For example: [[Q]] conjoins herself with [[U]] to form the digraph "qu"; [[H]], with [[C]], [[S]], and [[T]], form "ch", "sh", and "th" respectively; [[I]], [[G]], and [[H]] form the trigraph "igh"; two [[O]]'s conjoin to form "oo", etc.).
** Unlike letter teams, compound Numberblocks refer to themselves with singular first-person pronouns ('''I'''/'''me''') instead of plural first-person pronouns ('''we'''/'''us'''). This means that compound Numberblocks are individual Numberblocks even before being figured out, not just two Numberblocks fused together.
