Texas TI30XA Scientific calculator

I bought this as a replacement for my old calculator, which died suddenly. The button layout on this one is identical to the the old calculator, and they are as responsive as they should be. My best buy of the month!

As a secondary maths teacher I was frustrated that the standard scientific calculators confuse the students with features they will not need and they seem to always get such in modes they know nothing about. This is disastrous for students who are using all their cognitive power understand the maths. They don't need another thing in their maths lesson to be afraid of. So as my daughter is off to secondary school I looked for a simple one for her and I'm very happy with this one. The physical design if great. The buttons press with a pleasing click. The case is small and feels high quality. The display is clear. I only wish it were solar powered, but I have no idea how long the battery will last. The functions are plenty for higher GCSE and A level, although the outstanding A-level student will probably want a good graphical calculator. It's simple entry of calculations encourages splitting calculations into single steps using equal signs after each step, which encourages proper learning of the orders of operations. The most common functions are all on the face of the buttons with very few requiring a shift button.

I had a TI-30 during my University studies (Mechanical Engineering-Machine Building Technology), in the 80's, and it was for me the best pocket calculator. This one, TI30XA works fine, it is a great successor of the famous TI-30. It was a student limerick in my times, "At Strength of Materials you want to pass, buy a TI-30" - it has rimes in my native language. LOL, now, no one needs Strength of Materials.....

I like these Texas Instrument calculators. I had one back in '85 but it eventually packed up so I bought another one which was solar powered. That was difficult to use at home during the evenings as the 'solar power' didn't always provide a display under lower light levels, so I purchased this one which is battery powered and solved the problem. I have given 4 stars instead of 5 due to the fact that I can't remove the protective case that comes with it and which will have to come off to change the batteries in due course. I'll (hopefully) prise it apart with a lever of sorts but it'll last a few years before then and I don't want to risk damaging it right now. Regarding fractions, it finishes them off. For instance it will show 1-1/12th rather than 13/12ths for an answer which the Classwhizz FX-991EX does.* I think I prefer this calculator for that reason, although it is not as powerful. * Correction....the Classwiz will show 1/2+7/12 = 13/12ths or 1-1/12ths or 1.083333333 and back again by using the S-D and shift buttons. Apologies for wrong info.

Bought as a replacement calculator for my grandson. He's very happy with it. Would recommend.

I had one of these models when I did GCSE maths back in the 1990's. I only got rid of the original one I had because I could not get the back off to change the battery. I like this model because the layout and functions are very easy to understand and the display is very clear. The only thing I do not like with this new model is that the buttons are made of plastic rather than rubber, but I think it's because the original one I had did have rubber buttons so the mind does not like change. I am very pleased with this calculator.

This calculator is great. I would have not personally chosen this one, as it is tricky to save numbers on memory, etc. , but my uni needed this particular one every student to have.. If you are used to Texas calculators, you won't tell the difference ;)

I wanted a calculator that had a few more functions than a basic machine, particularly one that used the proper order of calculation (MDAS etc). I also wanted one with a reciprocal function for easy calculations involving electronics. This calculator is just the job- cheap effective and seemingly quite robust. It arrived within days and was well packaged against knocks and drops. It does the job and has a case which protects it when not in use/ Dellighted

Üniversite öğrencisi çocuğuma aldım. Sınavlara sokulması serbest, kullanımı rahat, tuşlarının tepkisi kesin, malzeme kalitesi yüksek.

Wie viele hab ich diesen Taschenrechner seit meiner Schulzeit. Da ich in einer Weiterbildung stecke und keinen mehr hatte war klar das Dieser wieder mein eigen werden muss. Er hat kaum Gewicht und ist somit super leicht, einfache Handhabung und viele Funktionen - für mich am wichtigsten ist die Prozent Funktion. Er funktioniert wunderbar, alles wie gewohnt und der Preis ist für das gute Stück wirklich billig.

Best calculator ever !! and OMG it's only 10 bucks ...Math/trig was the foundation of my job and this was my go to calculator throughout most of my working life. It's not programmable, but if you know what you"re doing - as you should !! - you don't need programmable. It's a great scientific calculator that will work for years and years. Laid out well and easy to understand, I'd love to kiss the person who came up with this - just hope it's a girl :) ...buy this calculator / you cant go wrong !!

La Texas Instruments TI-30XA è la calcolatrice scientifica per eccellenza, un vero e proprio strumento di lavoro basico ma incredibilmente affidabile. Perfetta per studenti di scuola media e anche superiore e per chiunque abbia bisogno di funzioni scientifiche senza le complicazioni dei modelli più avanzati. Punti di Forza (Semplicità e Affidabilità) 1. Funzionalità Essenziali Complete Nonostante sia definita "basica", la TI-30XA copre tutte le necessità fondamentali di matematica e scienze. Offre funzioni trigonometriche (seno, coseno, tangente), logaritmi, potenze, radici, e soprattutto, gestisce in modo eccellente il calcolo con le frazioni. È uno strumento potente quanto basta, senza essere eccessivamente complesso. 2. Costruzione e Durata La calcolatrice è un vero carro armato. È dotata di una custodia rigida scorrevole che protegge efficacemente i tasti e il display. I tasti stessi sono in plastica resistente e ben distanziati, ideali per un utilizzo prolungato senza preoccuparsi di usura o rotture accidentali. 3. Facile da Usare (Logica Algebrica) Utilizza il sistema di immissione algebrica (AOS), un metodo intuitivo che la rende immediatamente utilizzabile anche per chi è alle prime armi con le calcolatrici scientifiche. I tasti codificati a colori aiutano a distinguere le funzioni. 4. Alimentazione a Batteria Affidabile L'alimentazione a batteria garantisce una lunga autonomia e la tranquillità di poterla utilizzare in qualsiasi momento, a differenza di alcuni modelli solari che faticano in condizioni di scarsa illuminazione. Aspetti negativi per l'uso che ne faccio non ne ho trovati

Came in quickly and packaged well. works as expected. Sixteen year old son is as thrilled as he possibly could be to get a new calculator to do math... .. which isn't very, but the calculator itself is great.
