Weak in math? It's alright. PhotoMath is a nifty little app for you. Just point your phone camera at a math question, then it will give you the answer and show you all the steps to solve this particular equation!
Solving a math equation with a computer is nothing new, but it's a painful process to type the equation in these apps. With PhotoMath, now we can just take a shoot easily. All you need to do is to point your phone's camera at an equation. If it's solvable by PhotoMath, the program will not only provide a solution immediately, but it will also "show its work," step by step, to explain how the problem can be solved by hand.
The step-by-step guide is the best part of this app in my opinion. It is beneficial to students that struggle with solving math problems. Parents can also use this app when teaching math to their kids.
However, it's not that omnipotent. In fact PhotoMath has its limitation. It can only read printed text, and your handwritten notes can't be solved by this app. If you test it out on an order of operations equation, you'll find the app keep on mistaking the "X" variable as the multiplication symbol.
Oh yes, this is a good APP for math, but do never use it to cheat in your exam:)
