Approximations or exact values - why not both?

TI-Nspire CAS (Computer Algebra System) technology provides you and your students the ability to
perform both symbolic and standard numeric calculations.

The comparison screens below shows step-by-step, arithmetic, algebraic and calculus calculations as
they would be displayed on TI-Nspire CAS App for iPad and TI-Nspire App for iPad.

TI-Nspire CAS and TI-Nspire handhelds share almost all of the same enhanced graphing and computer
feature functionality. The CAS engine is built into the TI-Nspire CAS handhelds and Teacher and
Student Software exclusively.
