Photomath is one of the greatest app I’ve ever found on the playstore. The app is totally free of cost. Calculations are made very much easy due to this application. You just have to place the camera over the question and it soon calculates the figures and gives the answers just in few seconds. The pros are that you don’t have to type the whole thing in order to get the answer you just have to bring your camera over the paper or whatsoever on which the values ate written which is to be calculated.
It solves even the quadratic equations and Integration and Differentiation is also done by the app very quickly.
Mathematics is made very easy by this app as it solves the lengthy lengthy sums just is few seconds which doesn’t sounds less than a miracle for students.
