In Chinese/Japanese, there's 四 rocks in both base 10, and base 4. (8 rocks would be 二四 in base 4).

I think the concept of "base" is easier to understand when you include a numeral for the highest base (10 = 十, 20 =二十).

Of course, arabic numerals are more concise, using position to imply meaning (21 = 二十一).

Doesn't base 4 only go up to 三? Like binary is base 2 and only has 0 and 1. 四 would be base 5.

they already said that they have numerals for the base they use. from what I understood, basically imagine we use base 10 but have a numeral for it, let's say X. our numbers go like this:

1, 2, 3, 4, 5, 6, 7, 8, 9, X, X1,X2, X3, X4, X5, X6, X7, X8, X9, 2X, 2X1, 2X2, etc...

so i imagine it's similarwhen they use base 4:

1, 2, 3, 4, 41, 42, 43, 24, 241, 242, 243, 34...

mind that i have no knowledge on this and I'm only interpreting what i understood from the comment above.

Spot on. Good example! And 十 is indeed just X on it's side :D
