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.

App Idea!!!!Want to make your app BETTER read THIS!!

Ok, this app is amazing it does wonders! BUTTTT I have to pay for it to teach me how to do it like Bruh. I thought y’all got money’s from ads? Instead of doing that I have an Idea for Y’all. Instead of making people pay to learn how to do it, but You should have a learn option but not like the one you have now, the learn option should be an option that teaches you how to do it but instead you actually have to solve problems and rather you take a quiz on it and retake it as much as you’d like! And up you can make people pay for it as it will be “premium”. You could also include flash cards, and games to help figure the math type out!! People would definitely be willing to pay for an app that teaches good!! What you have now dose t do much for teaching but instead you can make a new and improved and FUN way to learn math, then you can have them add points to the equation whenever you get a question right! And then add an avatar that you can customize but you will need coins to buy whatever you want, you can earn those coins by answering correctly math. Or at least getting 7/10 or more right!!! Again this would main your app wayyy Funner and teachers could use it as a way to teach and would pay for the program!! So adding that would equal MORE MONEY towards your company!!! Let me know if you guys use this idea, and thanks for reading 🥺❤️💕
