Agreed all around,
Many other reviewers have already made the point, I can only affirm it. For the price, it’s a great calculator but the instructions are awful and very difficult to follow. I ended up spending $12 after the fact for replacement ink cartridges because not only are the directions/illustrations unclear about how to install the ink cartridge, but if one is not careful, the cartridge slips out of your fingers and easily becomes irretrievably lost inside the guts of the calculator. (I can hear it rattling around in there, but cannot get it out.) Be warned, local supply stores’ listing of replacement cartridges will not have this model listed in their stores, so be sure to ask and make sure that you get the proper replacement cartridge (the HR 100 is NOT the same as the HR 100TM; I learned the hard way.)

|A Machine You Can Count On,
For the money, and for general office use, this is a great printing calculator. I have owned a number of Canon and Casio printing calculators but I think I’ve found the best one to date with this Casio model. I am especially appreciative of the extra-large digital display.

|Calculating On The Kindle Is A Breeze Now,
If you’re not a math genius (like my husband), this is a great little app for your Kindle. All the basic functions are there, as well as percentage, square root, 1/x, memory, etc. You can also see the history of your calculation. In addition, results extend many decimal places (one result I got showed the answer to 16 decimal places). The numbers and symbols all match up nicely to corresponding keys on the Kindle.
Sure, if you want to figure the orbit of Pluto around the Sun in the year 2525, this is not the calculator you would use…..although my husband might be able to figure out a way. But for everyday needs, this is a good little calculator. Sitting somewhere shopping at Amazon on your Kindle? Just use the calculator to figure how much all those great books will cost!
Someone on here said not to buy the calculator, and to use some secret method on your Kindle. Well, I tried his method and my Kindle froze up and I had to re-start it. I then came here and bought the calculator, as I’d rather pay 99 cents for an EASY TO USE calculator than to attempt some alternative method that is a pain to use and causes problems.

|Very useful addition to your Kindle,
The person who gave this little application a bad ranking may be a geek and can hack his Kindle. There is a way to do that. But most of us are not so gifted nor do we want to be. Easier for us to pay .99 and be done with it. That said, this is a nice calculator. I especially like having the running tape. That’s better than any pocket calculator. In fact, one of the bad features to the otherwise handy little pocket calculators is that there is no running tape, so you can easily lose where you’re at if you have a lot of figures.
It takes a bit of practice to get proficient at this calculator. But it’s really nice. It’s the size of the screen. So just about anyone can easily see it and work with it. It’s a fully functional financial calculator. I find it useful when I’m looking up a price for a prospective client and then need to figure the bottom line.
The one thing I’d like to see is a way to make it pop up. Also, perhaps sometime Amazon will add a number pad to the Kindle. But that might be getting away from the way the Kindle was made to be used, to read books.
I read a lot of personal financial books and books on economics and often wish I had a calculator on the Kindle. So I expect I’ll get a lot of use out of this.
I initially gave it four stars because it doesn’t pop up. But after thinking about it, I figured that might not be a need of lots of people. Admittedly, it is somewhat important to me. I know I have a popup calculator on my Palm device.
So, when you’re reading a book and need to figure something, you have to get out of the book and into the calculator and then back. But I know that it might not be possible to develop an app for the Kindle that does that and so it’s not fair to judge it based on that criteria.
Otherwise, this is an excellent tool and I recommend it.

|Handy Calculator App – Recommended,
This “Easy Calculator” adds a simple calculator application and fills a void I wasn’t even aware existed since it gets used almost every time my Kindle is on. Here are my observations:
Pros -
+ Looks like a traditional calculator on the screen
+ Convenient to access
+ Inexpensive (a relative term, I know)
Cons -
- Key mapping has a slight learning curve, but easy enough once you get the hang of it
I am very happy to have found this useful app!
Highly Recommended!
