What’s the name of the app?

Photomath

What does it do?

On the photomath app open the app simply point your camera toward a math problem and Photomath will magically show the result with detailed step-by-step instructions.

Once you have the result of the sum you can see how it is worked out aswell to help you in future to work out how to do it.

Before I go on to the demonstration the negative is that the equation has to be clearly written.

 Image of app in use.

As you can see on the app all you do is take a picture of the sum and it will work out the result.

Are there any disadvantages?

A negative of this is that the sum has to be clear enough to be read by the app.
If you press the red bottom it will show you how to work it out and how to make it easier to work out.

Its light weight (it’s a app in your phone) and to download it, it is free.
