It is every day whole day, she do fly above maas. It is irritating for measurements on audio.

Happely there is room of some hours between, and sometimes 30 minutes when practicing above the populated area.

But some other question, what calculatoer can I best use as math is not mine strongest point, there are calculators who does set formula,s in as people write them, that is quite nice, and more easy.

bol.com | Texas Instruments TI-30XB Multiview - Wetenschappelijke rekenmachine

I always strugle with math, the formula,s did get wrong output etc. Need something to easy that. And no excel, I can not work with that program, I mean set it up.

regards

3 Chinooks in formation overhead on friday in the UK, as I picked my eldest up from school!

There must be some heavy flooding somewhere, relatively close. I've had probably 30 sightings this year so far, maybe as few as 3 or 4 last year.

As far as an pocket calculator recommendation, the Casio FX83 you show is excellent and reasonably priced (or it was back when I used one as a mature student, graduating 2015.)

Still, there is something in the old school FX 82b from the 90s, I had a friend who had one of these baby's

Google Image Result for https://i.pinimg.com/originals/70/b3/68/70b368a45483a8255d9e119dd6be9c64.jpg

That would graph plot and all sorts of other things that I never got the best of. The FX 82 has all I'd ever need.

Finally, I would say that I too struggle with maths. It's not that I am bad at maths at all, but there are many people who are far more fluent, practiced, or maths orientated than I.

Secondly, I would say don't give up trying.

Casio FX82 or the one you show can do all you will need and more.

If you try breaking each part down into separate calculations, when working with really long formulŠ, then you should be able to get the correct answer.

Working with 6 or more brackets, heck 4 brackets, is awkward.
