square roots
Numbers times themselves
A square root is a number that, when multiplied by itself, produces a given number.
The square root of 9 is 3, because 3 × 3 = 9.
Most numbers have two square roots—one positive, one negative—though the term usually refers to the positive one: What's the square root of 144?
The square root of a negative number requires imaginary numbers.
