Can the Mayan arithmetic operations be fully decoded from the Dresden Codex?

I'm studying the cross-cultural development of mathematics. The Dresden Codex is famous for its calendrical and astronomical tables, which imply sophisticated calculation. Scholars mention multiplications and base-20 (vigesimal) arithmetic. But is our understanding complete? Can we confidently say we know how the Maya performed operations like multiplication or division based solely on this codex, or are there still significant gaps?

As a historian of science who has worked with these texts, I can say our understanding is advanced but not complete. We can decode the numbers and recognize tabular structures used for calculations like multiples for calendrical cycles which imply operations. However, the codex doesn't contain a "textbook" explaining algorithms step-by-step. We have inferred operations like multiplication from patterns in the tables, but the specific procedural notations are still debated. Complete decoding requires triangulation with other sources, like the Madrid Codex, and archaeological evidence. We understand the what (results of calculations) much better than the exact how (their mental or written algorithms).
