CasioSL-300VC, Solar Powered Standard Function Calculator, Blue

This is the best calculator than the previous similar one used for years. Love the tax button that can be programmed for the correct tax rate where you live. Large display so can be easily read.

For the price, this is unbeatable. It's basically a work horse. Solar power guarantees that it runs forever.The keys are easy to press. Size is compact. It even comes witha flip cover!For the price, this is excellent. Super useful and practical .

Cute, works well and comes with a little cover

Works well, small size stores well among junk on desk

This is a nice, small inexpensive basic calculator for pocket or purse - it has a good looking and decent size LCD display, two way power, a handy tax function, and oddly (to me, at least), it also has a time calculator function (hours/minutes/seconds). The keys are easy to operate and it even comes in a variety of fun colors.Unfortunately, the "case" is kinda janky. It's just a binder-style affair with a strip of double-stick tape that I guess you're supposed to affix to the backside of the calculator, thus obscuring the backside's snappy color. Really? For the cost of that case, they probably could have made a sliding cover, or even a pocket sleeve.Second, the instructions explain the tax and time function, but nothing else. I mean, it's basic enough, but -Amazingly, this is the first calculator (out of tons) I ever owned that had this mysterious "triangle" key that looks like a "play" button.After digging around on the web, I finally learned that this key is a 'last digit entered erase' key, i.e., if you enter a number that has many digits and you enter a wrong digit, you use this key to erase the last digit you entered (it's a backspace key).Conclusion - love the calculator, but the case and instructions could certainly have been better. :)

Good calculator

The media could not be loaded. Solar Power shut down after 6 mins (should last for the next 2 years of nursing school plus some, absolutely love the large numbers, buttons function correctly no lag, love the low cost for the quality. Love the cover of the calculator to help protect it yet I can just throw it in my MacBook cover zipped pocket, purse, or backpack

There is very little information on how this calculator works. The manual describes how to set the tax rate as well as how to do time calculations. However, when I do the calculation 10 + 20% (not using the tax key) the answer shown is: 12.5, but it should be 12. I have even set the tax rate to zero. When the % button is used, it should work exactly as the % button works on all other calculators. It should have no relation to the tax button, with the exception of holding the button down for a few seconds to set the tax rate that's only applicable to the tax button. I don't understand how it's coming up with 12.5. I have multiple calculators with the % key and they all show 12, including my phone and Windows 10 computer.Update: I figured out what the % button is doing. It applies a "markup" to the value. This is not the same as some other calculators % key.With regular calculators, the add based on the percentage of the number you are adding to:12 + 20% = 14.40 This is arrived at by doing 12 * .2 = 2.40 + 12 = 14.40But this calculator instead does a "mark up" of the number which works like this:Say you have an item that you want to sell for $12. But you want to list it as 20% off the regular price.With this calculator you do: press AC then 12 + 20, press % key = 15.00.We can check our work by doing: press AC then 15 x .2 = 3 and 15 - 3 is 12.The % key on this calculator should be marked MU instead %. But since this key has two functions,1 to set the tax rate, and the other to find a markup, they just left it %. The manual does not indicate that the% sign functions as a markup.This is a great calculator for calculating the tax for you so you will know what the total cost will be.
