Sharp EL-W516TBSL Advanced Scientific Calculator with WriteView™ 4 Line Display & Solar Power

I've had this awhile, didn't review it right away as I was not sure of its features and use. I bought this to replace a TI Scientific calculator I had for a long time. This had a lot more features, had to really play with it to understand how to use it. If I was a millenial or younger I probably would have picked it right up, but I'm much older. I like that it has a solar cell and a battery, haven't had to replace the battery and its been a couple of years. The feel of the buttons seems cheaper than my old TI, but it works well, very functional, display is not always the brightest but in decent light it is very clear and readable. Has a slide on cover that fits on the back when in use and then slides off and onto the front to protect the buttons when needed, good design as it won't get lost or broken that way.

It seems a bit perverse to not just use the calculator tool built in to most major operating systems, but sometimes you just need to do a quick calculation without wading through menus. This does the important bit twiddling operations on buttons (doesn't have rsh/lsh/rol/ror, but you can cope) and is equally convenient for fixed point/normal calculations. Good readable screen (man I wish it was backlit) and a sturdy cover for sticking in your laptop bag. Pretty sure this is the best option outside a vintage 16c Weird limitation of 9 binary digits means you can only convert hex up to 1FF

Functionally it is well conceived. Very powerful, and lots of functions without digging into menus. Unfortunately it is not so sturdy like Casios out there.It feels somewhat plasticky and cheap.

I bought one of these when my very old calculator died. As I am constantly performing scientific and engineering calculations, I needed something more than the standard "math-box". I particularly liked the solar cell on the unit as it seems to extend the battery life quite a bit. I'm still on the original battery - something that never happened with my old unit. I was always installing new batteries in that, even though it was an LCD calculator. This is a great buy for someone who uses the scientific and engineering functions of a scientific calculator and puts a lot of "mileage on a calculator.

I got this as an upgrade from my TI 30Xa. It does what I need and so much more! Like others have said, it’s like a graphing calculator, but without the graphing part. It has integrals, summations, exact answers (pi, fraction, and square root), statistics, scientific constants, vector calculations, matrix calculations, a basic equation solver, and much more. And even though it doesn’t actually graph equations, you can input y= equations and it will give you a table of values you could use to manually graph. It can be a bit tricky to understand how to use it, but once you get the hang of it, you will be flying though menus. Overall, this is, in my opinion, the best scientific calculator you can get.

Good product.

This is nothing more than a paperweight for my desk. I should have stuck with TI, but just barely even that. There is no manual included with this calculator and the product page at Sharp has a link to a 404 error (page not found) for the manual so there's no way to get one. I bought my first TI-30 calculator in 1976. That came with a small printed manual with probably around 200 pages of instructions and samples. There was no Internet in those days so it was, no doubt, expensive to include a printed manual but TI did so. In the TI-30 manual there were examples of trig problems, present and future value calculations, interest and net payment/mortgage calculations, etc. The book was practically an Algebra course. Unfortunately, today, even TI manuals are terrible with only basic instructions on the keys and modes, etc., only 43 pages, or so, depending on model. But at least TI has manuals; Sharp, on the other hand, doesn't. Whatever calculator you are considering, I'd find the manuals and instructions, and review/find them to the level of detail you feel like you need to have, before ordering. Otherwise, you'll be heading off to the UPS store, burning fossil fuels, to do an Amazon return as I will have to do. Since I can't drive due to surgery, I may not even get out before the return window is over. Should have bought a TI or HP. I'll have to follow my own advice and find manuals first, before trying to order again.

I gave up my TI-83 and 84 and switched to a TI-30X because it was approved for use on all of the standardize tests that require calculators without advanced memory and storage. Why did I never go back to a more advanced calculator?? Who the hell knows! A colleague of mine recommended this calculator and damn, I have been missing out! The best part of this is a one button change from decimal to improper fraction to reduced fraction. This has been a game changer in checking my kids math homework with the improper and reduced fraction displays! I love this calculator!

Works perfectly, as described. Very happy with the product! Thank you. ⭐⭐⭐⭐⭐😊👍

Very good calculator for studies!
