What is square rooting?

A square root of a number is a value that when multiplied by itself gives the number. Example: 4 × 4 = 16 so a square root of 16 is 4. Note that (−4) × (−4) = 16 too so −4 is also a square root of 16. The symbol is √ which always means the positive square root. Example: √36 = 6 (because 6 x 6 = 36)
