Shelf price said £6.87, when scanned at self service came up at £2.50!

This was in the Galashiels extra if anyone is local.

Go bargain hunting!

These things were at least £15 when I was at school.
HOT!
#2
I paid full price last week, a bargain,

this doesn't add up!

i saw these today in the reduced bit for £6.87 and was going to get one but thought nah!!!

there'll not be many left at this price ..................that's only a calculated guess though.
#7
Cracking calculators, especially for A-levels. I had one, and it was good for surds etc. because it shows it in 'natural display' mode. Highly recommended.

Tesco have had MULTIPLE pricing errors this week haven't they

perhaps they haven't got a calculator, or there pricing computer is letting them down again -

When I went to school they were about £30.- . And they could not do as much.

Oh, and it snowed everyday and I had to cycle in my shorts to school; obviously after milking the cows and feeding the pigs.
#13
An FX-85 just got me through my Physics degree - bargain price.
#14
These remind me of my school days, excellent kit, and much more expensive in those days, came handy for writing the equations etc on the back cover lol!
#15
nice find, repped
#16
IT's worth noting that the price cut is likely because this model has been discontinued. It is being replaced with the FX85GT+:

That said this is an excellent price for a very good calculator for any student up to GCSE level - I personally recommend the FX991 for A-level or above...
#17
Wouldn't even remember how to use mine nowadays!
#18
The ones with graphs and stuff on them were about £100 when I was young, they were for the kids who got higher than a C in their GCSEs :P
#19
Nice price, these little babies can also survive being covered in dichloromethane, with only minimal melting.:whistling:

If you own an fx-82es, fx-83es or fx-85es, you can upgrade it to a fx911es, It allows you to integrate/differentiate/solve quadratic equation etc.

1. Check what version you have - on the back, just above the made in China sign, there is a letter in a circle: if it’s a B, unlucky because you can’t do the mod, however if it’s an A you can.
2. Open up your calculator - on the back there are six screws, using a Phillips screw driver, remove these and then lift off the back, revealing the circuit board.
3. Find the P4 jumper - on the circuit board there are six screws, between the middle two is a little white P4, to the right of this is a small split silver circle. Take your graphite pencil and colour this, making sure the whole thing is covered.
4. Put it back together-now put the back, back on and screw the screws into the holes.

This procedure basically makes the calculator confuse itself about which model it is; models only differ at the jumps.

Basically my whole A-Level maths class had these, they're awesome. Great deal.

I still use it at Uni too :D

It's fine for degree level - these are the only calculators my department (engineering) allow for use in exams! We do have to buy them for £10 from the union shop though :x

Be very careful if you upgrade to anything other than fx-83/fx-85. Many (perhaps most) institutions only allows those suffixes in exams. This is a cracking price for an fx-85. I have one just like it and it cost me about £15-20 (I can't remember exactly). It's seeing me through my maths degree just fine (although thinking about it I only really use it for statistics).

The 991 is definitely allowed at GCSE and A-level.

The only advantage it gives over the 83/85 etc. is solving equations numerically and differentiating/integrating numerically. All graphic calculators can do this, so if an exam allows those, the 991 should be allowed also. They cannot deal with algebra i.e. solve symbolically, as the really expensive banned calculators can.

I have both a 991es and 85es and the button labels are different, so before anyone goes rushing to try this upgrade, may want to consider that. If the upgrade simply turns the calculator into a 991, some button labels will no longer correspond with the function of the button.

This is a great price anyway, fantastic calculator.

Great calculator using atm on my Further maths A level :)
#26
I dont need one (Algebra FX 2.0 and TI84+ already) but might keep my eye out as a good day to day calc. (And to try the mod)

I used to teach in a school which had these and one thing to note with these is there is an issue, or perhaps just a 'thing to note'... When you put in the square it will calculate it after BIDMAS, i.e if you do 3x2^2 you will get 36 (i.e. (3x2)^2 or 6^2) as the answer rather than the real answer which is 12 (3x4)... To get around it you need to input 3x(2)^2 instead iirc!

What annoyed me was if you put in -2^2 the answer it gives is -4 not 4... caused lots of issues for the kids!

can someone confirm if these are solar power. , then again my batterry powered ,sharp calculater still works, left school 1997. i want one of these babies could not afford these.
#28
Dual power I believe :-)


(As in solar AND a battery)

Yep, dual powered. :)

Have this. It's a very good calculater. The only downside is that you need very good lighting in the room, otherwise it becomes difficult to see the figures because theres no backlight.
#32
Has anyone actually found one at another store yet?, going to my local tesco in a min, will be goof for my uni work
#33
For Girls (who don't need a complicated calculator), Tesco have Text FX500 Scientific Calculator for £1.

Edit: For girls because its Pink.

Also a good price, but... they aren't DAL or VPAM meaning that kids find them a little harder to use (eg. instead of tapping in sin 30, you'd have to tap in 30 sin).

Nice offer but none left at my local 'extra' stores. :-(

By Clicking Shift, then setup, then going down to contrast you can chnage it so there is very high contrast and its a lot clearer.

Would recommend this calculator - very good and an excellent price at 2.50!:thumbsup:

Its £2.50

I'm not going to tell you how cheap that is, YOU do the math

:D

Thanks, this worked a treat. Could still be better with backlight, but then cant complain with solar power and at least its readable now!
