Buy a ten-key printing calculator
Read on for tips on how to choose your perfect 10-key.
Choosing your calculator
Before you buy a calculator, you're going to want to find one that has the features you like best. From the simple to the complex, ten-key calculators are most useful when they have only the features you need and want, and not the features you'll never use.
Most useful basic features
- Two color printing is a great option, because negative numbers print in red. You always know at a glance if a number was added or subtracted.
- Display size is important if you have issues with near- or far-sightedness. Also, the distinctness of the digits is important, so that a quick glance is all you need to recognize the displayed figure.
Keys matter
Larger, comfortably spaced keys are better for accuracy and speed. Avoid springy keys at all costs. If you buy a calculator and the keys take too much pressure to tap adequately enough to register, send it back to the store. I once had just such a calculator and my accuracy was about as good as my ability to dial a phone with my eyes closed.
Key groupings are important too. It's always nice when the calculator separates the multiplication and division functions from the addition and subtraction.
