"Hmm... This Magic is certainly interesting. How did you come up with the idea to put these things into tables for calculation?" What Valentino had produced was an arithmetic table.
What Valentino called "magic" was, in fact, an arithmetic table. It was a product born from combining the arithmetic knowledge Robson brought from his past life with Mage Falan's own understanding.
When Robson first arrived, he discovered how people in this world did arithmetic. They used the common language, representing numbers with characters. They would list a series of characters to derive a new one, then use the magical understanding that everyone possessed to interpret the new character's meaning.
Robson had first recognized Falan's immense value precisely because of his arithmetic knowledge.
