Galois’ edict emerged from a mathematical predicament. In the 1500s, mathematicians had studied polynomials like x2 − 2 and x4 − 10×2 + 22. They had tried to find simple formulas that would allow them to calculate the roots of those polynomials — the values of x that make the equation equal zero — but could only find them when the highest exponent was no greater than 4.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

It is unfortunate formatting for the polynomials is lost in the blockquote. Would unicode characters make it more readable?
