Tesco Scientific Calculator- 10 Digit Display- GCSE A/AS Level- 56 Scientific Functions

It arrived on time got a nice case with it well worth the money. Came with batteries. Would buy it again

I am a GCSE Maths teacher. I bought 3 of these to use as spares with my students. Firstly, one out of three didn't work. Either it was broken or the battery was flat so I received a refund.Secondly, the functions do not work the same way as a standard Casio scientific calculator. The operations cannot be edited on the screen as you type so the order of operations is not taken into consideration like on more complex calculations. If you're studying GCSE then you will realise that this means your calculator will not follow "BIDMAS" rules.Also, if this was a suitable calculator for GCSE study, you would be able to type in a formula included substituted numbers in brackets and press "equals" once at the end to get your answer. This calculator will not do this - it functions as a basic calculator which performs each function sequentially as you press the buttons. For example, to find the square root of 9, you press 9 then the sq rt button, like a basic calculator. A proper scientific calculator (such as a CASIO EX85 GT PLUS) will allow you to type the square root symbol and then place the number (or calculation) underneath, much like you would write it. A Casio also has fractions buttons that are worth their weight in gold to a student trying to make their calculations more efficient and accurate. I don't work for Casio but their products are clearly superior.I genuinely think that if you buy this calculator for GCSE Maths, you will be putting yourself or your child at a disadvantage compared with other students. Most other students nationally will have Casio calculators that perform BIDMAS order correctly and have editing functions. For the sake of your/your child's maths grade, make the investment in a £8 calculator rather than this one at £2.50.This one is fine for adding up and multiplying and other practical tasks. It's no good for anything scientific or operations higher than Grade 3/E.

My daughter is very happy with the calculator because it will help her at school. The only thing that I was upset about is that the batteries inside were dead, I had to replace them.

Bought two as presents and was happy to see the quality of the calculators when they arrived. Solid built, working without any problems. Happy purchase.

Good for the low price i bought it for may end up buying another as has tiny screen and doesn't tell me what sum i did.

Bought this for our son to use while preparing for his GCSE's however some of the functions don't work such as the square root and brackets buttons

Cheap but does the job for 14 year old who loses everything.

Calculator was received in expected timeliness. Unfortunately calculator fails to turn on. Batteries checked and they are fine so therefore a technical issue with the calculator.Update- Seller has rapidly actioned the refund so 5star for customer service.
