There are also some findings about the Indus Script

The majority of academics who have researched the Indus Script concur on several issues, even though its decipherment has not yet been accomplished.

Typically, the Indus Script was written from right to left. In the majority of instances, this is true, but there are few exceptions in which the writing is bidirectional, i.e., it moves in one direction on one line but in the other direction on the following line.

It has been determined how specific numerical values are represented. A downward stroke was used to symbolize a single unit, and semicircles were used to denote units of 10.

The Indus Script blended phonetic value with word marks and symbols. A "logo-syllabic" writing system is one in which some symbols represent sounds and others indicate concepts or words. This opinion is supported by the discovery of 400 or so signs, making the idea that the Indus Script was purely phonetic improbable. The Indus Script, however, might only be phonetic if the theory that the hundreds of signs can be condensed to just 39 is accurate.
