Editors’ Choice

Every now and again an app comes along to blow your hair back and make you believe you’re living in a science-fiction future. Photomath lets you point your camera at the problem and a step-by-step explanation (and answer!) instantly appears on your screen. Triple-digit multiplication? Photomath’s got it. Linear and quadratic inequalities? No problem.

A VERY good tool for math.

While there are still 1 or 2 math topics this app isn’t exactly able to help with as of yet, its a WONDERFUL app that can solve about 90% of math problems, be them common algebra or highest and hardest level college equations. Nevertheless, you want this app on your side when doing math of pretty much and and all kinds. Its main function allows you to take pictures of math equations and, incase you accidentally have parts of other equations in the picture you took, you can crop them out as soon as you snap the picture, and it solves the equation for you as soon as you hit the ‘OK’ button. It also has a calculator where you can manually enter equations and have them solved. Its useful incase you realized you wrote an equation wrong, because you can just go right to the calculator part and fix it, as all the parts of the equation the app saw in the photo gets immediately put in the calculator. The best part, in my opinion, is the last function where it tell you exactly how it solved the equation, and it even lets you view every single step and gives you a brief but good explanation on what’s happening in the step. If you also scroll down while in the same function, if you took a pic of an equation that need to be graphed, you can actually see the equation graphed out for you. Its a very nice app and i HIGHLY recommend.

Best math app I’ve ever had!

Ok to start this off, I wanna say this is easily the best math app I have ever had. I’m in 8th grade and I’m learning a lot of new and confusing stuff that I don’t understand. Photo math breaks down the problems for you and it’s totally free! My math teacher recommended this app for me because he noticed I was really struggling with my math homework. When I got home from school that day, I downloaded it and I was really impressed with this app overall! All I had to do was take a picture of my math problem and it would pull up the answer. I could see if I got it wrong or right, and if I got it wrong, Photo Math broke down the problem for me so I could better understand it. This app has helped me understand math better and helps me with challenging homework. (This app is great as long as you’ve already done the problem and your not cheating.) Don’t get this app just to get the answers to all your math problems. The app overall doesn’t have many problems, it doesn’t glitch or freeze up. Overall I love this app and recommended to many students in my math class! They love it too!
