Every once in a while, I come across an app that makes me go "Wow!" It's a rare occasion these days, so when it happens, it means that the app is seriously impressive. Such is the case with AutoMath. Here's what AutoMath does — it uses the built-in camera to solve your math problems. That's right, you take a picture of an equation, and AutoMath will solve it.
Ultimately, AutoMath could make the creation of algorithms, programming, or schoolwork a lot easier. At the moment, AutoMath supports:
- Square roots
- Basic algorithms
AutoMath will also soon implement the following:
- Equation systems
- Scan handwritten questions
The last bullet point does indicate one of the few caveats to using the current iteration of AutoMath — it doesn't recognize hand-written equations. So, if you want this app to solve your math, said math must be printed out. I've tried handwriting an equation (my penmanship is horrible, mind you) to no avail.
With that said, let's see how AutoMath works.
The installation of AutoMath is as simple as 1+2. Just follow these steps:
- Open the Google Play Store on your Android device
- Search for AutoMath
- Locate and tap the entry by S2dio
- Tap Install
- Read through the permissions listing carefully
- If the permissions are acceptable, tap Accept
Once the app is installed, you should see a launcher on the home screen or in the app drawer (or both). Tap the launcher and walk through the welcome screens until you find yourself on the AutoMath main window (Figure A).

Using AutoMath is very simple — you open the app, place your equation within the rectangle (Figure B), and tap the Answer button.
Solving a simple equation with AutoMath.
AutoMath can do quite complex equations. However, if an equation is unsolvable by the app, it will open up an equation editor so that you can edit the formula, and AutoMath will attempt to solve the problem again (Figure C).

The equation editor also serves as a built-in calculator, which includes a number of functions (Abs, Addto, And, Apart, ArcCos, ArcCot, ArcCsc, etc). Tap on the CALC button from the main window, and then tap on the FUNCTIONS button in the top right corner to open up the listing of functions (Figure D).

Tap a function to have it added to the calculator. Enter the necessary data into the function (Figure E) and continue on with your equation.

If you happen to be using AutoMath in a low-light area, you can tap the LIGHT button to fire up your device's flash to illuminate the equation. There's also a feature to mute the sounds app (in case you're working in a quiet area). Another nice feature is that AutoMath retains a history of problems solved (or not solved). You can scroll back through them for later reference.
One thing you must know about AutoMath is that capitalization of letters does matter. Here's a perfect example of this:
x is a variable, whereas X is the symbol for multiplication
With that in mind, you can't expect AutoMath to solve:
X = (y + 2)/(3 x 4)
In the above equation, AutoMath will assume the leading X is the multiplication symbol and not a variable. Change the X to x and you'll see AutoMath solve the equation (Figure F).

Who needs calculators when you can simply point and click your way to solving those complicated equations? Give AutoMath a try and see if it doesn't make your busy life a bit easier.
