Calculator: Scientific

Calculator is the scientific calculator Android was missing — a modern, meticulously crafted math workbench that replaces every calculator app on your device.

From a quick arithmetic check to solving quartic equations, inverting 6×6 matrices, fitting regression curves, or graphing 3D surfaces, Calculator handles it all with a single fluid interface.
