When a Ten Key Calculator Is Better Than a Calculator App
A Ten Key Is the Better Choice More Often Than You Think!
It's a given that at some point you're going to be adding numbers and you're going to use the app on your phone (or computer). But the app on your phone has a lot of limitations and is usually only good for a quick two or three number job.
A Ten Key Is Better When You Need...
Speed and Efficiency
A ten key calculator is designed for rapid entry of numbers, and its layout and large keys make it faster and more efficient to use than a computer keyboard or the small buttons on a calculator app on your phone or tablet. How many times have your fingers slipped and you've had to redo the whole thing because of one dumb mistake? Or think about that one finger typing...
Do you really want to try to add up a bunch of receipts on something like this?
A ten key calculator is often more ergonomic than using a computer keyboard, because you can keep your hands in a comfortable position while entering data. This can help reduce the risk of repetitive strain injuries such as carpal tunnel syndrome. Can't really compare this to a phone or tablet app, but one finger typing is usually slow and awkward for more than a few numbers.
A ten key calculator is small and lightweight, making it easy to carry with you wherever you go. That's even if you need to carry around a printing calculator and an AC plug. This can be especially useful if you need to perform calculations on the go, such as when working on a construction site or in a warehouse.
A ten key calculator is a dedicated device that is designed for a specific purpose, meaning it's typically more reliable than a general-purpose computer or calculator app. It won't crash on you, and is not likely to experience other technical issues that could disrupt your work.
A ten key calculator is a standalone device that is not connected to a network or the internet. Maybe this is a stretch, but there is definitely some truth to it in these days of easily hacked devices and computers!
