loss calculator and which one?



For GCSE, AS and A-level courses you will require a scientific calculator. The use of various types of functions on calculators are often restricted in GCSE, AS and A-level papers. If in doubt, check with your teacher or examinations officer that the calculator you intend to purchase is allowed for use with your syllabus.

GCSE Calculators

In general for GCSE a calculator MUST NOT have the following

  • databanks
  • retrieval of text or formulae
  • QWERTY keyboards
  • built-in symbolic algebra manipulations
  • symbolic differentiation or integration, language translators
  • communication with other machines or the internet.

I would recommend the Casio FX-85 ES calculator as it is easy to use, powerful and excellent value.

For A-Level the Casio FX-991 ES calculator

AS and A-Level Calculators

Generally for AS and A-level you can use a graphics calculator but it MUST NOT have a facility for symbolic algebra, differentiation and/or integration.

I would recommend the Texas TI 83+ calculator

Beyond A-level

There are some excellent calculators that can do symbolic algebra, differentiation and integration along with many other functions suitable for engineers, surveyors, maths and science professionals.

As a teacher I use the HP 50G calculator

Casio FX-9750GII Graphic Calculator
