# Casio fx-83ES Scientific Calculator £2 instore @ Sainsburys

This is the calculator used by most secondary school students during GCSE and A level. Sainsburys usually sell this @ £7.99 and I have seen this as low as £3.99.

I found this in the Rice Lane store this morning and bought all 6 that were left. Before anyone gets upset I am not going to sell them on, I am a teacher and will distribute these in my classes to help kids with the rock solid calculations I set them

Hope this helps some people out there.

Sorry cold 4 me.

The Pound shops are full of crap ones, at least these are branded ones. I'm giving the OP a bit of heat for a decent price plus rep for the fact that its helping out the kids in the class who haven't got one - well done!

If these Casio ones are in the Poundshop for £1 then that's a steal. I've only ever seen the non-branded calculators in there, that in my professional opinion are not very good/sturdy.

(What I personally like about these as a teacher is that because over 90% of my students use them or share them the layout is familiar to all of the kids. They are comfortable using them and there is less hassle in class because of this. They are also the ones we give out to kids who forget their own in exams - another bonus because they don't have to panic about not knowing the layout of the calculator in the exam - when some students traditionally freak out at the slightest thing. I remember one going into a blind panic because when I told him the exam lasted "30 minutes", he was furious that another teacher had lied and told him it lasted "half an hour".)

I have a degree in electronics and I agree that casio calculators are by far the easiest to use. When trying to do calculus and complex transforms in an exam you have enough to worry about without trying to remember how your calculator works.

This also has the excellent feature of allowing you to scroll back through your calculations to see where you screwed up.

Others swear by Texas Instruments calculators though so I guess its down to personal preference.

HAHAHAHAHAHAHAHAHA!!!!! :w00t:

That took me a while! :thumbsup:

I bought a decent Casio one for my Math's GCSE. I still have it now after finishing my degree.

HOT deal

To be clear - these are scientific calculators and do lots of mathematical computations including algebra, cube-roots, sin/cos/tan, and the like.

I still hanker back to my youth with the FX-7500G casio clamshell...

Don't confuse this calculator with the ones in pound shops, this calculator has a natural dot matrix display that will show a fair bit on the screen at once.

£2 is a right bargain.

The School That I Used To Go Were selling Ones Just Like These For A Fiver:x

Fantastic, I think you deserve some rep just for that! :lol:

They are just clearing their back to school stock to make room for halloween and xmas.

but calculators ARE for xmas. at least, thats what i get everyone!

cracking price, the only calc i was allowed for my physics degree was a casio like this. still got it now.

Hot deal, heat & rep to OP

Oh no wait, that doesn't work on a calculator! :whistling:

I found some calculators wouldn't follow the BODMAS rule(I think it was that) for calculations and the way you had to enter things varied to what you were actually trying to do.

Personally I'd be very wary buying a child an over complicated super programmable calculator because I found doing A-Levels that the people who had these just relied so heavily on the calculator and had no basic grasps of the maths they were doing as the calculator did all the work for them. In my class, this resulted in them ultimately getting lower grades than those of us with the £6 calculators we'd had for years.

Bargain though for £2 as I have lost my Sharp

If I recall Casio's were the 1st to have fraction calculations on them also (The envy of the class). All the teachers / lecturers had Casios and also were quiet intuitive to use for things like Binary calculations and other techy stuff.

If I was buying a calc. for my son, it would most probably be a Casio. £2 is a steal for this kind of quaility product.

That said be careful parents, it's very important to get our kids to learn to add up and not use a calc. for the simple stuff! Certainly gonna need one for trigonometry etc. at O level though fo rthe complex stuff (We've moved on from slide rules now I guess!)
