1, CAS series calculators (such as TI-NspireCAS) have advanced mathematical functions such as calculating algebraic expressions, calculating symbols, solving equations and calculus. CX series calculators (such as TI-NspireCX) provide some mathematical functions, but they do not fully integrate CAS functions.

2.CAS series calculators have more powerful notebook computer functions, including multi-window browsing, electronic document viewing and editing, programming, etc. The notebook computer of CX series calculator has relatively weak functions, and is mainly used for basic mathematical calculation and graphic drawing.
