Overview
A middle or high school student working through algebra and trigonometry gets fraction calculations, standard deviation, trig functions, logarithms and exponents. Solar power runs the LCD, and a hard cover protects it.
The test approval list covers the common school exams, and the cover suits a backpack. The listing names both solar power and AA batteries, so the real power source is unclear.
Who it's for
Students in middle and high school math. Graphing course buyers need a different class.
Pros and cons
- Permitted on major tests

Performance notes
A single-line LCD shows one entry at a time. Solar cells run the display in room light. The long list of scientific functions covers school algebra and trigonometry.
