What does the screen on top of the calvulator do?

That is the solar panel which converts solar radiation (light) to electricity, to power the calculator. There are two almost identical models, this one with the solar panel and another which runs on batteries. Note you only get a basic instruction booklet, the full manual has to be downloaded from the casio web site.

Where is the “SD” button on the new version of this calculator?

Use the key to enter the SD Mode when you want to perform statistical calculations using standard deviation. In the SD Mode and REG Mode, the key operates as the key. Always start data input with (CLR) (Scl) to clear statistical memory.

My previous casio calculator had an arrow button to delete just the last digit typed-can this calculator delete one number without using the c or ac

On this Casio calculator there is a DEL button to do the same function you are describing, very easy!!

Perfect For Secondary School But A Lot Of Complex Buttons/controls

Great item. Perfect for secondary school. Battery life ok. Size is good (fit in my pencil case). It looks like it can last for a while. 'complex buttons' may take some time getting used to pressing (not easy to understand even with instruction booklet). Value for money is good.
