To be honest, I'm not disappointed one bit by the calculator. A decent set of functionality that seems to work, a manual that's properly written in English and of course the $1 price tag. There have been calculators that have been sold which cost far more than this price and which lacked some of its functionality (e.g. Commodore calculator) or had a manual written in Engrish.

For the price in particular, it's really amazing. In the mid-1980s, my school-issued calculator was about $70 (nearly $180, inflation adjusted to 2021) and it had no more functionality than this device. The only real factor that makes this calculator more expensive than an equivalent 4-function is the yield (and hence price) of the ASSP under that epoxy blob. The housing and keypad are not going to be significantly different in cost, assuming the device remains the same approximate size.

Interesting that this appears to compute using floating point numbers. That requires a lot of decoding to display the numbers on screen as well as a lot of circuitry behind the scenes. Floating point rules allow the encoding of repeating numbers which then get rounded up during decimal decoding for display. Which is why your trick of 1/9*9 works. Most calculators use fixed point math with BCD circuitry. It's simple, cheap to implement, and requires very little circuitry. In fact, the memory cells, the display digits, and the ALU lines are all balanced out into a WYSIWYG (What You See Is What You Get) type of configuration. This is a fascinating amount of computing power for $1. I'm impressed they can pull it off.

This product couldn't be imported into the EU (RoHS/mercury), so maybe that's a contributing factor to the cheap price.

It didn't even directly do percentages. 1974, and $70 then was equal to about $300 today. The only reason I had it is because it was a prize in a contest. $1 for a scientific calculator today.

Yo you got a shout-out in the newest technology connections, great job man.

this got me through fourth grade, not a bad calculator. switched to TI from fifth grade to present day, sophomore in college.

Now I know where to go buy my scientific calculator for Uni in Jan 2022...thanks for the heads up on this little Dollar Tree gem!

employees: "HEY HEY, WHAT ARE YOU DOING! STOP USING THAT CALCULATOR"

0:46 This reminds me of how I passed by some small market stall where they had a Canon basic calculator that they used while it was still in the packaging and had the price sticker from when they bought it at a Popular.

Amazon UK have that exact calculator for a shocking £4.95! (But it does come in a real cardboard blister pack.) Alternatively, you can get one branded as a "Texet fx500r" for £3.95 and enjoy the anticipation of wondering which of the three lucky-dip colours you'll get!

I LOVE your calculator vids!

Wow, I had that exact same calculator, I probably bought it about 7 or 8 years ago, it’s cool to know they still make the same model!

I have an ancient mechanical Friden calculator that does multiple/divide and a method of doing square roots. (there is a model that directly does square roots). Does that count?

I see a CPLX notation above the right-pointing arrow key. So the negative root thing is legit - that calculator appears to support complex numbers. There must be a way to switch between the real and imaginary parts on the display. Check the manual :) (I bought one of these a while ago too, but the battery is long dead).

Cheaper to buy a new calculator than a replacement battery! I have one of those, I forget if the complex numbers are for imaginary numbers, or x/y polar versus angular conversions.

the cplx feature just reassigns two keys, a and b, allowing complex input. you can do complex arithmetic (+, -, *, ÷) by inputting the real part and pressing a, then the imaginary part and pressing b, and you toggle which part of the result is displayed using the same two keys. without cplx, those two keys are for polar-rectangular (and vice versa) conversions. cplx is just for arithmetic, it can't do real (no pun) complex maths. the reason it works in the video is he's actually doing the 3rd root, which is allowed in real numbers.

@@bobblum5973 True, but throwing away a perfectly good calculator just because it needs a new battery just seems stupidly wasteful to me. I just bought one of these cool little calculators today and when the battery dies I'll probably go ahead and replace it.

Professor I had in college was talking about back in the 80s he was buying a car and the dealership was offering a free calculator with purchase of a new car, touting it would be the LAST calculator he'd ever need and own. I think he's still upset to this day about the false advertisement.

I’m just chillin in my car after a long day of school. And this is the funniest thing I have seen in a while. A video about a calculator made my day lmao

I guess you can consider those really early relay computers as "mechanical scientific calculators"

Thanks. I love these things! I have 2 of them. I don't even care that I can download calculator apps for my phone (I have several of those, too). I'm just old-school enough to appreciate real calculators... and value! tavi.

"I'd buy that for a dollar"

The only guy I know of who can make an 8 minute video about a calculator that is very interesting.

Of course everyone with a smartphone has this capability built in, so I guess the use case for this is... ...math exams?

If you do a lot of calculation at your place of work, having a calculator with a real keyboard is essential. Real keys provide some cushioning that hitting a touch screen all day does not. They also provide better haptic feedback. I don't need to see a calculator screen while doing calculations. My fingers can feel if I have hit the wrong key, just as they can when typing on a real keyboard. Finally, a cheap calculator like this is much cheaper than a phone if it is destroyed in a hazardous environment. I do serious calculations in Matlab where they can be repeated. I will usually grab my hp-48s for one off and preliminary calculations. If I am called out to the factory floor, I will take one of these dollar store cheapos with me.

You was pressing 2nd function when first doing negative roots, and that function is cubed root. You can have negative cube roots.

Yeah, I goofed the goof. But Numberphile had a similar mistake in his hilarious Gaxio calculator video.

That's an amazingly capable calculator! It's _bizarre_ that they can manufacture and distribute it, _and_ make a profit, for one dollar.

I think the date code inside shows a 2018 calculator. There may be 1 ,000,000 left over when it was sold for more, these are old stock items.

This calculator used to come with a cover that snapped onto the front, but even without the cover it's an incredible value. It can also spit out random numbers, and you can string the digits together to get longer numbers. The reason that some calculators show inaccuracy in the later decimal digits is because all calculators convert to logarithms to simplify the calculations. Multiplication becomes addition, and so on. It all depends on how many digits of irrational logarithms are programmed into the calculator.

Pretty impressive for $1!

I went from a TI-something graphing calculator to something like this and used it through my junior and senior years of high school. I couldn't keep graphing calculators. People loved stealing them. They didn't steal the plain ole scientific calculator and I did just as well in honors trig and honors calculus than with graphing calculators.

These were the spare calculators in my freshman algebra class.

I have the same design of calculator which I bought from poundland in the UK for one Pound. Mine is ever so slightly different though. It has orange rubber sticky-out bits, and it came with a lid which can either cover the buttons or be clipped on the back. The thing lives in my garage, and has taken huge amounts of abuse, but it just keeps on working. It has outlived two casio models costing an order of magnitude more money.

When I was little we had this handheld wood grain calculator with red numbers that where not LED.. it was the old school tube looking numbers. I remember my parents would only let me play with it if they where right there because I might break it and it wasn't cheep.
