If you know how to use it, it can help with complex algebra problems. However most HS teachers are more comfortable teaching on the Ti-83 family (Ti-84 Plus is the best in that family). So unless your very good at teaching yourself by books or have very good friends / teachers who knows the Ti-89 by heart and want to share, you would most likely do better staying with a Ti-84.
