Different types of calculators

Please be aware that our support videos for questions requiring a calculator are primarily based on Casio calculators, and we advise teachers to be prepared for slight differences if their students use other brands.

For example 

  • In our iteration videos, we tell students to press the “Ans” button, but on Sharp calculators, they would need to press SHIFT+= to get this function.
  • Videos for questions requiring multiple steps may show answers to intermediate calculations in surd form to match the Casio display. Other calculators may show these answers as decimals.
