Great printing calculator for an office full of men. This calculator takes a beating and just keeps on coming back for more. We have five of them now and my boss wants me to get two more. Love them!

Got this for use at work after our last calculator that we had for about 15 years had broken. Stuck with Casio because of the quality of the last one and so far are NOT disappointed. This calculator feels VERY nice, works perfect, and is a really great size for doing some basic accounting at your desk. Couldn't be happier!

Nice touch if you do 10-key by touch. Seems to be durable, and it's easy to load the paper tape. I personally like that the ribbon is on 2 spools rather than a roller or a cartridge. Works fast and printout is clear. Really good value for the price.

this is our 3rd one not due to a bad machine but ours were old and we replaced as they quit working. ours are used a lot everyday and so I think they will last about a year maybe longer.

It didn't work right and kept printing all kinds of numbers that I did not enter. Decided to buy new because I like this unit better than the other brands and had one before that lasted about 5 years. It is very quiet and fast, and the keyboard feel is really nice. I should also say that I'm a self-employed bookkeeper and have used Many calculators. This one is my favorite in 41 years using various brands/models.

Casio dr-210tm calculator is just perfect printing calculator, the calculator works great, however don't go by the instruction booklet. It is impossible to understand. I was a little disappointed that it did not have a battery backup so there is no time setting and I have to set the date every day.

I had a Casio 10 key (maybe an old term?) for over 20 years and was used to the layout of the keys so when mine died I got this one because the key layout was the same. Yes, as another reviewer said, it is big, but all good quality 10 keys are big. I don't find it any larger than the one I had so I am happy enough with the size. I really like the new and improved extra large display and the keys are much softer and the machine is much quieter. I'm happy with it. As for the difference between this one and the other one on Amazon that appears to be the exact same. Other than the price, I'm not sure what the difference is. This works for my simple bookkeeping needs.

Two things you should know about this casio calculator:
1. It does some pretty spectacular business calculations. If you are figuring margin, need a running total, need to add or remove tax, or need to figure against the same number several times in a row, it can do it, plus a bunch of other great stuff.
2. It's comically large. Seriously, this thing is the size of my head (and I have a pretty big head). Some of the other reviews said 'larger than expected'. They probably would have been more accurate to say, 'oh, my God, how did they even deliver this thing?' Seriously, it's the size of a Buick.
I love what it can do. I will definitely be keeping it, as soon as I can clear out the extra bedroom to make some space for it.

I wanted a semi-inexpensive desktop printing calculator. This meets my criteria! The keys are sturdy and don't wobble to the side when pressed. It makes a quiet, short, deep sound. The tapes print nicely. After all my comparison shopping, I'm glad this was the purchase made.

Great calculator. Works great and lasts. I've gotten 3 of these for our staff now. They all like them.

Use the total key (* or T) to sum your numbers

The easiest way to think of a ten-key calculator is as an adding machine (many of which print this nice little tape for you as proof that you did indeed add that staggering column of numbers correctly). Its sole function is to add numbers. Positive numbers, negative numbers, all kinds of numbers. If it's of decent quality, it will even tell you how many numbers!

The item count is a neat feature that can also stupify if you haven't had much experience with a ten-key--or if you just didn't bother to read the instructions that came with your calculator. However, I'll explain all that in a few moments.

Adding numbers on the ten-key

This is not as intuitive as you might think. I recently answered an email where someone asked me if I had it wrong below. Trust me. I don't. I'll include the email and my response below my tutorial to help make my point clear.

Okay, so we want to add some numbers.

6+5+9+8

Now, do I have to tell you to turn on your calculator? (Please don't make me. I'm not sure I can handle the stress.)

1. Press: [ C/CE (or C) ] [ C/CE (or C) ]
2. Press: [ 6 ] [ + ] [ 5 ] [ + ] [ 9 ] [ + ] [ 8 ] [ + ]
   See your total there on the screen now? I hope it shows 28. If it doesn't, start over at #1 above. Quickly, now! We're moving on here.
3. Press: [ * (or T) ]
   Nothing happened, did it? That's all right. Nothing was supposed to happen. If you had hit the clear button before you pressed the *, your calculator wouldn't have printed the total or concluded the calculation.

Adding and subtracting numbers on the ten-key

Wow, that was easy, agreed? So, now let's change things up a bit. We'll add and subtract some numbers.

Casio Adding Machine Ink

6+5-9-8

Ten Key Adding Machine

1. Press: [ C/CE (or C) ] [ C/CE (or C) ]
2. Press: [ 6 ] [ + ] [ 5 ] [ + ] [ 9 ] [ - ] [ 8 ] [ - ]
   See your total there on the screen now? I hope it shows —6 or 6.— depending how your calculator shows negative numbers. If it doesn't, start over at #1 above. The thing to remember here is that the calculator is going to ADD everything you input with the keys. So if you want to subract something, you have to enter it as a negative number or, if it's easier to remember, think of it as telling the machine you want to add into the total the number 6 you just entered, you want to add in the 5, take away or subtract the 9, and take away or subtract the 8. But you can't tell the machine to do these things with a number until you've entered the number itself! ***[see below for some further clarification]
3. Press: [ * (or T) ]

A recent email about adding and subtracting on a ten key calculator

The email

You provide this example:
6+5-9-8
1. Press: [ C/CE (or C) ] [ C/CE (or C) ]
2. Press: [ 6 ] [ + ] [ 5 ] [ + ] [ 9 ] [ - ] [ 8 ] [ - ]
Shouldn't the + that I highlighted in red actually be a minus?

My response

10 Key Adding Machine Instructions

Actually, no. Think of it this way: the 6 is added to the total (starting from 0), the 5 is added to the total, the 9 is subtracted from the total, and the 8 is subtracted from the total. With the ten key printing calculator, this is how you have to input the numbers to get the answer. :)

Another Way to Think of Adding and Subtracting on the Ten Key

Here's a short bit of further clarification for those who still might be having trouble with this concept. Think of it like this. You've just punched in a [ 6 ], now you have to tell the ten key what to do with it, so you punch in a [ + ], then the [ 5 ], and you have to tell it what to do with that one, which again is to add it, then the [ 9 ], which you must tell it to subtract so you follow with a [ - ]!

We're going to move on to mixed calculations now, because multiplication and division is that same old stuff you're used to with a pocket calculator, but wow, isn't it going to be fun to add, subtract, multiply and divide within the same calculation! Move on to mixed calculations...
