Frequently Asked Questions

  • What is the difference between the Casio fx-991ES PLUS 2 and the fx-115ES PLUS 2? — These are the same calculator sold under two different regional names. The fx-991ES PLUS 2 is the international designation; the fx-115ES PLUS 2 is the North American designation for the identical model. Both have the same 417 functions, Natural Textbook Display, and solar + battery power. Either name may appear on Canadian exam approved lists — they are interchangeable.
  • Is the Casio fx-991CW allowed on Canadian university exams? — The fx-991CW is a non-programmable scientific calculator and is generally permitted on exams that allow non-programmable calculators. However, exam policies vary by institution and course. Always verify with your professor or exam invigilator before purchasing. The fx-991CW is the successor to the fx-991ES PLUS 2 and offers additional functions including a spreadsheet mode and QR code connectivity.
  • What is the difference between the Casio fx-9750GIII and the fx-CG50? — Both are Casio graphing calculators, but the fx-CG50 is the higher-end model. The fx-CG50 features a high-resolution colour display and a 3D graphing function not available on the fx-9750GIII. The fx-9750GIII has a monochrome display but is lighter, less expensive, and sufficient for most calculus and statistics courses. The fx-CG50 is preferred for advanced engineering, 3D visualization, and users who want the best display quality.
