    Bet­ter dis­play but small­er fontThe dis­play has bet­ter res­o­lu­tion and con­trast from the pre­vi­ous gen­er­a­tion — but the input-line font has been reduced by about 30%. Would have giv­en 5 stars if Casio had retained a ‘lega­cy’ font size. Apart from that, cal­cu­la­tor is intu­tive to use and has all the func­tions that i will ever need.

    Good but needs solar!I though all cal­cu­la­tors had solar pan­els in them these days. This is a good cal­cu­la­tor and the bat­tery life is quot­ed as 2 years at 1 hour a day but to change the bat­tery you have to take the whole back of the cal­cu­la­tor off and life could be extend­ed with a solar pan­el. It is non pro­gram­ma­ble which is essen­tial in many exams etc.

    exact­ly what you’d expect…I was look­ing to order 2 cal­cu­la­tors for my sons to take into their exams, and these seem to suit them. They fit the bill. The only gripe I have (I should have checked more close­ly) is that this cal­cu­la­tor does­n’t have solar cells for repow­er­ing them­selves so they will need new bat­ter­ies at some point. My fault for not check­ing more closely.

    Bet­ter Con­trast than the fx-83GT PLUSI bought this becaue I’m doing a maths degree and I think my pre­vi­ous cal­cu­la­tor must be ready to give up the ghost any time soon. The screen is the same size as the PLUS mod­el, but the out­put text is small­er — HOWEVER, the con­trast and sharp­ness is way bet­ter, so over­all, the screen is much, much eas­i­er to read. I wish it had a back­light (or front light, or ANY light) but Casio has­n’t seen fit to fur­nish us with one yet, so we’ll all have to keep squint­ing at the tiny num­bers and hope that one day they’ll lis­ten to us.

    Daugh­ter com­plains that it lacks a 10-but­ton, fair pointOur daugh­ter need­ed a new sci­en­tif­ic cal­cu­la­tor for her new sec­ondary school and I was tasked with find­ing one. Well, the cal­cu­la­tors I was allowed to use in high school and col­lege were fair­ly basic at the time and the more advanced,scientific ones quite expen­sive. To my sur­prise sci­en­tif­ic cal­cu­la­tors these days are friend­ly priced. How­ev­er they also seem quite advanced.. It made me realise that I won’t be able to help my daugh­ter much with explain how it works. It seemed to be filled will load os of new func­tion­al­i­ty and has a big­ger, much more help­ful dis­play. I’m get­ting old and so is my trust­ed decades-old Casio sci­en­tif­ic cal­cu­la­tor, that I can t always count on, on spe­cial equa­tions. though it is still going strong and I still do use it from time to time even in these days of handy apps and iPhones.The only thing is that most of my ancient sci­en­tif­ic cal­cu­la­tors looked quite sleek pow­ered by solar cells and were much, much thin­ner and lighter, which would be eas­i­er to car­ry along to school. But then again as with many thins cal­cu­la­tors may be ugly on the out­side, but it is the inside what counts!

  6. Mrs. Lynne Patterson

    These are great for school needs, and son actu­al­ly told me school use these as sparesThe box states these are accept­ed by schools for use in exam­i­na­tions at school, so it gives chil­dren a chance to get used to their cal­cu­la­tor and the func­tions, and then to use it with­in their exams, would high­ly rec­om­mend this for any par­ent look­ing for a cal­cu­la­tor of good qual­i­ty — I have bought cheap­er ones in the past and hence the need to replace as they break easily.

  7. Bri­an Aicheler

    Impor­tant to be con­ver­sant with the dis­play con­fig­u­ra­tion set­tings.This is one in a range of cal­cu­la­tors that may be used for any sec­ondary school maths for GCSE and A lev­els and beyond. It does not have a graph­ics capa­bil­i­ty but the func­tions that are avail­able cov­er a wide range of appli­ca­tions. The dis­play is con­figuarable for lin­ear pre­sen­ta­tion or as a math pre­sen­ta­tion found in text­books. It is impor­tant to pay atten­tion to the dis­play con­fig­u­ra­tion as not all func­tions work in all all confugu­ra­tions. How­ev­er, it is easy to use once the dis­play con­fig­u­ra­tion is mas­tered. The Casio range in prob­a­bly the de-fac­to stan­dard for cal­cu­la­tors and it is easy to oper­ate dif­fer­ent mod­els as they all use sim­i­lar set­tings. I would ful­ly rec­om­mend this cal­cu­la­tor for school and col­lege alike.

  8. Grace

    Need­ed a new sci­en­tif­ic cal­cu­la­tor ASAP and this did not dis­ap­pointI had a very old casio sci­en­tif­ic cal­cu­la­tor (20 years old!) that even­tu­al­ly gave up the ghost. Unfor­tu­nate­ly it stopped work­ing 5 days before a big exam which I need­ed a cal­cu­la­tor for, so after search­ing online I brought this one. Its a great cal­cu­la­tor. Works as it should and is easy to pro­gramme to the dif­fer­ent modes if you need to. Casio is a great make. I saw this cal­cu­la­tor in a super­mar­ket a week lat­er and it was dou­ble the price I paid!So this is a great cal­cu­la­tor for a great price. Hope­ful­ly it will last anoth­er 20 years!

  9. Be A San­ta c/o Pat Tallman

    Easy to use and does the job.This is a GCSE rec­om­mend­ed prod­uct and I can see why. There appears to be a func­tion key for every­thing set at that lev­el. The keys respond quick­ly and don’t stick like on some oth­er cal­cu­la­tor, which is impor­tant when doing cal­cu­la­tions. I like it. Well pack­aged and came on deliv­ery date spec­i­fied. I can’t com­ment much on the bat­tery life as I have only had it a few days. how­ev­er, it worked when I turned it on. I see that it is sup­posed to last up to two years but I sup­pose that is depen­dent on use. I will have to wait and see.
