Excellent price. Found in Lower Earley in their back to school section. I'm guessing it's nationwide.

Scientific calculator for a pound?

This model (and it's sister, the 83GT PLUS, which is the same but without the solar panel) are great calculators. It isn't that teachers are trained to use any particular model, but these are particularly easy for students to use because they show you what you've typed in in the way it would be written (e.g. fractions are written as fractions, even if they have functions inside them). This also means when a student gets a syntax error, it is easier to spot and correct. Additionally, there are a few extra functions that most other models of scientific calculator do not have e.g. express a number as a product of its prime factors and also giving answers as surds.

Any scientific calculator will have enough functionality to get a student through GCSE Mathematics, including the new specifications with numerical grading which will be sat from May 2017. But others are harder to use, particularly some of the old TEXET ones, where to find sin 30 you had to type the 30 before pressing the "sin" button.

It is also useful for students to have the same model as the other students they sit with so that they can help each other learn to use it.

If your son/daughter will be at high school in September and doesn't yet own a scientific calculator, I would strongly encourage you to get either an 83GT-PLUS or an 85GT-PLUS.

The Casio models I used at school and University were exactly like that. Then when the display started to fail about 20 years later, I have to adjust to the new syntax.

Seriously, there is no substitute for this calculator. Especially not that awful iphone calculator...just don't...

Also, same price in Tesco

Edited by:"gav989" 19th Aug 2015Put into a cheap calculator

1 divided by 3 =

Then multiply by 3 =

It should give 1

But it will give 0.99999999

Apple mac does the same..
