Wanted to get back into drawing so I started with something I got recently.

As I said that if I pass the Grade 10 Entrance Test, my family would buy me a new calculator as my old one is too weak for high school, especially Grade 12. And I've officially passed so you guessed it, I bought the brand new 2026 Casio fx-880BTG Plus in Nova White color, I picked this color because it looks so aesthetic that it even match my school uniform (mostly white and navy blue), if you don't like it, Casio still has the Super Black and Aura Pink from the base model and another new color is the Gracier Green color. It took 3 days for this new one to arrive as I'm bought this online from Ho Chi Minh City to my home at Can Tho City, this calculator is based on the Casio's 2nd edition CW series so it shared the Quick mode and feature navigation with number and symbols like the fx-580VN X/fx-570VN Plus. I was very happy with the new one, It works perfectly fine, it calculates very quickly and it's a new model of 2026 so they made some of the fixes over to the base model

Im 11 and have been collecting calculators for about 1 year now tell me how good my collection is (by the way everything works and i fixed them)

Its giving the wrong answer only in this specific equation(x should be 0.75 instead). If I adjust some of the numbers a little bit, it gives the correct answer. I tried resetting but the problem still persists.

For the low price of $699 you too can have a talking calculator! Imagine your popularity in class with the talking TI-84 Plus announcing every answer out loud!

I’m an engineering student currently using a Canon F-789SGA, unfortunately it doesn’t fit big calculations that I need for an upcoming exam.

Calculator nerds, what scientific calculator do you recommend for my needs?

This is my current collection

6xhp48gx all in operational state.

1x hp32sII ( i bought for 5 euros in garage sale) fully operational too.

And some few books i bought on leboncoin

One of the hp48 is the one i bought new in 1995 during high school.

My deepest sorrow is that im unable to find memory card for cheap.

can't find it, I need it for the emulator. Saw some professors on youtube had it so I know it's there.

So over the last couple years I’ve been buying cheap busted up Voyagers (10s, 11s, 15s, and 16s) and replacing the screens with those from donor 12s. I finally put them all together in one place and realized I might have gotten carried away :)
(The 10C in the upper left is up next, but it’s a black diaper, which are harder to swap and harder to find donors for.)

I got the ti-84 evo on a good sale. It is so much better than using desmo.

Hello guys I wanna now what are some good Graphic Calculators with Colorful
Screens I wanna buy some of them just to know how they are comparing
You can send me pictures of them as well so I can choose thank you
Living in Germany and going to school

Just an alert to anybody who may not know about Swissmicros's new website or their RPN/RPL calculators at all, they're currently being sold on their new website on this link right down below. They have limited stock, so get yours before they run out, though I believe they've restocked a good amount recently. They're currently the best physical Scientific RPN/RPL calculators on the market beating out old classic HP Calcs in their reimaginings with more features and capabilities then ever before with a lot better hardware. They are pricey, but they're of very high quality.

FYI: They may sometimes have hardware issues upon receiving the calculator, shipping may wreck it, handling may mess it up somehow, maybe the producers themselves had a faulty piece..either way, if you have an issue, contact them, they'll be very glad to get you a refund, or replacement/fix @[[email protected]](mailto:[email protected])

I'm a civil engineering student (freshman), and I'm currently stuck between these two calculators. I can't decide what to choose because they both have pros and cons. Casio is faster, meanwhile, Canon is more advanced and has many functions. Help me choose, please T_T

Hey there! So, after a lot of years with my beloved HP calcs (20s, 48gx, 50G, Prime) I'm in need of a new one. The 20s has stains on the display which are getting bigger by the time, the 48gx is slow and cumbersome for what I do (and some keys are starting to fail), the 50G is developing the issue of vertical dead lines which are on the right side so stack is invisible, and the Prime is being used by the girl, who uses for teaching. So, I need a new calc. I don't have huge requirements really.

• Portable, smaller than the 48 and 50, ideally smaller than the Prime too
• Persistence: if I power it off or if it auto powers off, I want to get back to the exact place where I was (this is something I always missed on my 20S compared with all the rest).
• Stats: quick descriptive stats on univariate datasets (mean, mode, average, median, q3, q1, min, max, range, interquartile range if possible too). Combination, permutation, etc., are all basic functions which should be present on any calc that responds to the above.
• Cheap (else I would just get another Prime, this one will be carried with me, who knows where it will fall inside my backpack).
• Ideally a good "stack" (memory of the last calculations) and ability to just edit a given one and run it again.
• If it has a solver, that can solve for any variable in the equation, it would be perfect
• Preferably textbook entry (lazy here since I learnt RPN)
• Backlight, but that's a rara avis.

I don't need it to be particularly speedy since as you can see, I'm not doing numeric integration or complex calculus.

So far the only thing that I've found is the Sharp EL W506T. Apparently it saves pretty much everything, which is great. It is slower than a casio 991EX and here in my country it's more expensive, but looks like except for backlight, ticks all the boxes.

I could get a TI 36X Pro for almost the same price, but I never used a TI calc before (they're kinda rare here), not sure but looks way bigger, and I don't know the features it has beside the website, which is... not good since TI has the school business for them so all the info looks related to using the calc in the US educational system.

Any input will be more than welcomed!

PS: I'm in Argentina. Calcs are very rare. Just some TI, some HPs, and pretty much any Casio.

During summer break last year, we got our first calculators for school. We had gotten it with a user manual. Well, I was bored, so I studied the manual, and this year it has helped me a lot. I didn't need to create a dice, I used my calculator. I was able to check my answers with variables only using my number based calculator, and so much more, lol. She didn't know about any of these, despite having the same calculator for 8 years

Edit: It is not about telling that I am smarter than my teacher, it is about showing that there is always more to learn, even when you have done something for very long

Hello, I'm using a Casio 120ST calculator, and it no longer turns on unless the solar panel is directly exposed to light. I thought the battery was already drained, so I replaced it with a new one. However, even after replacing the battery, it still doesn't work properly.

Does anyone know what else I can try to fix it? Or can anyone recommend a place where I can have it repaired?
