บท 136: Numbers, Currency, and Practical Tests

"Numbers are directly tied to trade and economics," Elyon explained. "If every country used a different number system, it would cause chaos. Even if you don't understand the language, as long as you know the numbers, trade can happen."

That made sense. Damien realized it was probably the same reason why Arabic numerals were globally recognized in his own world.

Feeling a little envious of how knowledgeable Elyon sounded, Damien reached over and patted his head again.

"Wh-what are you doing? Stop—stop that!" Elyon squirmed.

"Can't help it. It's your fault for being so cute, Ely."

"D-don't say such nonsense! Look here—pay attention! I'll write them again. This is 1, this is 2, then 3, 4, 5, 6, 7, 8, 9, and finally 0."

"Got it," Damien nodded.

"Next, you'll also need to learn about currency," Elyon continued.
