I just downloaded a new app called PhotoMath that I found on yahoo news (click on link Math App below to check on the latest updates for your device):
This app, as you can read, will solve math problems by just putting your phone over it. I am assuming many math teachers reactions will be, “NOOOOO!!!!”, but others may see an opportunity for students to check their work and teachers need to be very cautious during exams.
Check out the app and make your own opinion. Just know that this technology and others are out there, for good or evil!
