Reviews
"After almost two decades, my desk calculator from Office Depot finally stopped working."
"Great hand-held calculator with larger keyboard and larger numbers in the panel which is great for those of us whose vision isn't what it used to be."
"This is a great handy calculator and it works fine."
"I used it on my very busy loan officer desk for 17 years, spilled coffee, soda, and ice cream on it and it still worked! I wiped off the underside of the keys and washed the silicone pad and the reassembled calculator works perfect, like new!!!"
"The buttons on this one are just placed slightly differently (due partly to the fact that this one has an 'off' and the other didn't), so I continue to make errors, thinking I've pressed a decimal, when in fact I've pressed the equal sign instead."
"I bought this one because it had the tax rate function and two-way power. I, also bought the Casio SL-300SV solar powered standard function calculator at the same time."
"I share the opinion of other reviewers here who lament that this calculator does not easily allow you to add percentages."
"Prior to purchasing this calculator I failed to notice that the decimal key was in the bottom row center key."

"This calculator is substantial, almost as big as my 20 year-old one with sticky keys."
"It takes a single AA battery and when in the light the solar array "supplements" and helps to reduce the battery consumption. Nor does the solar array CHARGE a rechargeable battery."
"This calculator doesn't have any fancy keys for extreme calculations."
"My mom's calculator stopped working and I jumped on Amazon to purchase another."
"I love this calculator."
"I also like the layout because I am finding that there a lot of different key arrangements on portable calculators and not all are laid out the way I like it."
"They used RPN math (reverse Polish notation) Now that I am retired I need simple."
"Basic simple calculator."

Reviews
"If you are wondering if you can do some sort of math function on this calculator, you probably can, and a quick google search will show you how to. As I said, a quick google search will turn up most any answers, but it would have been nice to see some more help come with the device."
"I will say that the touch pad part of the cap volatile can be a little annoying at times but nothing to worry about. I can leave it for two-three weeks without charging and still have energy in the tank."
"Great graphing calculator, just keep in mind that this model is the TI-Nspire CX CAS."
"I used this calculator for some of my calculus courses in college and it was my life saver."
