The ten mathematical problems that still have no solution - 1. Riemann hypothesis - 2. Hodge's conjecture - 3. Navier-Stokes equations - 4.
It helps alot with homework :)). So far every math problem that I took a picture of and has came back the right answer and good results and I am pleased with it of the apps doesn't answer all my questions for me so today I won't be reading this 5 out of five stars.
