These can be very helpful when you're stuck on a problem and don't know How to add fractions with variables.
Love this app it's great it has a calculator and you can make photos of your math problems and it will solve them right away. On top of that it then explained how to solve it myself.
If your math isn't that good, this is the app for you. It can easily read the pictures even if the texts are so small, at first, this app was not useful because you had to pay in order to get any explanations for the answers they give you.
Just a little tip for those who say it doesn't work, if the picture captured something diffrent than you want it to re-write the problem in neat handwriting and try it again, it's so easy to solve the problem and gets a very acurate answer with all the steps.
