Perform calculations on fractions without converting them to floating point numbers. Floating point numbers that exceed the number of decimal digits are rounded or truncated, generating a relatively small inaccuracy. The solution is to use The Calculator with fractions capabilities.

This is to the people who created this!

The app is useful for helping children with their homework or if they’re homeschooled but I upgraded it with an iTunes card and I did NOT receive the “no ads” there was continuous ads throughout the app and I did NOT receive the fraction calculator at all I’m very VERY disappointed I would if I could get a refund or you people better get your app together don’t think this is a joke many people have rated 1 and 2 stars and looks like only 2 people used 5 star I feel sorry for them, but if you’re thinking I’m using a different divide such as phone then you’re wrong I’m using APPLE iPad and there’s no glitching or lagging.
Please try to fix this! Thank you :)

Imagine if your pencil played ads while you wrote

Because that is how annoying this app is. This app is everything that’s wrong with our digital world. Who would have thought that you could hijack the simple abacus, that pure and noble device, and turn it to the eye of Sauron. I just need to calculate a currency conversion on my eBay purchase, friends, I’m not looking for 5 insane tricks to make my love handles disappear. I don’t know which young, starry-eyed computer science grads were co-opted in making this, but to them I say friends, sometimes your dignity is worth more than the $12 an hour they’re paying you 996. In summary, if you’re looking for a reason to quit the world of the living and join a prepper vault deep in the wilderness, this app is for you. Otherwise, do what I’m about to do and re-learn multiplication by pencil and paper.

The calculator itself is fine but is plagued by ads

I've been using this app for years, no problem, the banner ad was always fine as it was out of the way. This was until the **video** ad was introduced. A VIDEO ad in a calculator app??!! The whole point of having this app is to quickly solve a little arithmetic with no pause, except you now have to wait for a video ad to load and wait for it to finish. Another thing that bugs me is that I can't listen to music while using this app, instead, the "Calculator App" takes over my sound?? And when I play that, it displays the sound as a link to a website? All I need is this app to not interrupt my music and not shove a video ad in my face every few minutes.

Developer Response ,

Thank you for contacting us with this issue. We are aware of this issue and hope to be able to have this fixed in a future update. Unfortunately I can’t make any promises about when this will be, as we are constantly working on a multitude of projects and bug fixes. We will do our best to have this problem fixed at some point though.

Our apologies for the inconvenience.
