Illustration 1: the form created for this illustration was created by Arithmetic Addition. The best angle of the volume arrangement was where multiple surfaces were covered. The representation was in the style of Yakov Chernikhov. Each face is represented in distinct lines and curves with fenestration in different textures.

Illustration 2: the form created for this illustration was created by Arithmetic Division. The angle of the arrangement was similar to that selected by Alberto Sartoris in his representation. This angle covered different facades as well as the central void. Each façade was represented with colours concerning the direction they were facing. More focus was created on the roof by the eye view of the illustration.
