Excellent scientific calculator.

I bought it for my son who is in 6th Form. It was recommended by his math teacher. it is meant to to be used in his A levels math classes. This calculator is similar to a small computer. It can deal with calculations related to probability and statistics, it can plot graphs and a lot more. My son is happy with it and he finds that it is easy to learn how to use it.

Hi there,

I have looked into this and can advise that this calculator does come with a battery included.

Thanks for using Argos Q&A.

Hi there Newton,

Yes, this calculator tells you when you're on solar and when you're draining the battery.

Thanks for using Argos Q&A
