You're a really lazy student and you have to do math homework. You also have not much time. What would you do. â€“ I guess you would take out your smartphone and would search for that exercise on Google. But that's not necessary any more!
The simple solution has the name â€œPhotomathâ€. It's an app that helps you solving math exercises by recognizing all the number with your camera. Following the Play Store description it can do the following tasks:
- Decimal numbers
- Linear equations
- Equation systems
- Several functions like logarithms
More complex tasks like integrals should be supported too, but for them there aren't detailed step-by-step solutions available yet. (But according to the developers this will come soonâ€¦)
I used the app myself sometimes and I also tried integrals but it just worked sparely. But nevertheless the math keyboard is really good! You can easily write complex formulas with multiple fractions etc. without any big problems.
But instead of using this app you should use your brain! (Or use the app, if you're as lazy as me ?. It's worth to have it installed!)
