    The Ti-89 has many time saving features. Foe physics, math, and any engineering field, this is a must have tool. Solving multi-variable equations, linear algebra matrices, or differential equations takes half to a quarter of the time. It does take some time to get used to all the functions and how to impliment them using the correct syntax, but well worth the learning time.
