Math-Girl1-PhotoMath, a free app, lets you take a picture of an equation and get an answer plus the steps involved. (Does not recognize handwriting.) Assuming you already have it on a screen somewhere, this is easier than re-typing the mathematical expression at sites like PhotoMath already has 11 million downloads for the iPhone and Windows Phone version. That’s a lot of downloads but it didn’t work for us. You try it. An Android version is coming soon.
