Don’t worry if it’s been a while since you brushed up on algebra, geometry, trig, or (gulp) calculus. The next time you’re stuck, let these apps show you the light.
See the solution with a snap
‣ Take a picture of any printed math problem and Photomath and Mathway will figure out the correct answer and explain how to arrive at the solution. Photomath will also graph out the problem, while Mathway has the know-how to tackle statistics, linear algebra, and chemistry.
Graph it
‣ GeoGebra is a powerful graphing calculator with a very simple menu bar for plotting functions and polar and parametric curves. Desmos plots equations, lines, and parabolas and lets you save your graphs so you can refer to them later.
