Simplify a radical

  1. Type the number and press enter. 12 comes back as 2√3, the exact simplified form, and the program ends on its own, with nothing to escape out of.

  2. Press enter for the next number. The calculator reruns whatever it did last, so the square root prompt comes right back.

Good to know

  • Perfect squares come back as plain numbers. 36 prints = 6, and √144 gives 12. If a number has no square factor to pull out, like 7, it says "Already simplified" instead of leaving you guessing.

  • Whole numbers only. Decimals and negatives get a reminder instead of an error screen.
