Overview
Plotting functions, solving equations and running statistics from one keypad is what students do with this calculator. The screen shows the graph and formula together, and a case protects it in a backpack.
Two calculators with graphing in one pack covers siblings or a spare for exams. Exam approval is not stated, and power comes from batteries rather than solar.
Who it's for
High school and college students who want graphing without a high end graphing calculator. Test takers should confirm the exam's approved list first.
Pros and cons

- Wide function list

Performance notes
The display shows the graph and the formula at once, which helps when checking how a curve changes. Modes for angle and display switch quickly between trig in degrees and radians.
