Frequently Asked Questions

  • What type of calculator do I need for university in Canada? — Most Canadian universities permit non-programmable scientific calculators for exams. The Casio fx-991ES PLUS 2 (also sold as the fx-115ES PLUS 2) and the newer Casio fx-991CW are the most widely used and accepted models. Graphing calculators are generally not permitted on university exams unless specifically allowed by the course. Always verify your institution’s calculator policy before purchasing.
  • What is the difference between a scientific calculator and a graphing calculator? — A scientific calculator performs advanced mathematical functions (fractions, trigonometry, logarithms, statistics) and displays results on a multi-line screen, but cannot plot graphs. A graphing calculator has a larger display and can plot functions, solve equations graphically, and run programs — but is typically not permitted on university exams that allow scientific calculators. Choose a scientific calculator for most exam use; choose a graphing calculator for coursework and assignments where graphing is required.
  • What is a printing calculator and do I need one? — A printing calculator is a desktop calculator with a built-in thermal or ribbon printer that produces a paper tape record of every calculation. They are essential for accounting, bookkeeping, cash reconciliation, and any application where a verifiable audit trail of calculations is required. If you work in accounting, finance, or retail cash management, a printing calculator is a valuable tool. For general office or home use, a standard desktop calculator is sufficient.
