I hate using the calculator on my computer and I need to use a calculator often so I decided to buy a calculator. While in Walmart I saw this LeWorld calculator with larger buttons and it was cheap so I decided to get one.
It has an 8 digit display, auto power off and memory functions. It has a nice large display and large numbers making it easy to read. The display portion also comes forward or lays down depending on what is best for the user. The number buttons are black while the buttons for the math signs are light grey. That’s a very nice design feature.
The directions on how to use this calculator are on the back of the package along with examples of how to use it with the math equations. This is a pretty easy calculator to use even if you use the memory function keys.
It supposedly runs off solar or battery power. I hope it continues to work on solar power because to replace the battery means removing nine screws in the back!
Update On Mar 30, 2010: This calculator stopped working for me after using it for about a year and a half. I probaby could have got a replacement but I just bought another.
