The TI-30X IIS is a two-line scientific calculator built for high school and college math and science classes. It shows the entry on the top line and the result on the bottom, so you can check what you typed before you commit. It runs on solar with a battery backup and comes with a slide case. It is a step up from a basic four-function calculator but far simpler than a graphing model, which is what most standardized tests require.
