## What number is both positive and negative?

0When 0 is said to be both positive and negative, modified phrases are used to refer to the sign of a number: A number is strictly positive if it is greater than zero. A number is strictly negative if it is less than zero. A number is positive if it is greater than or equal to zero.

## Does a square root have 2 answers?

It has multiple answers so why do we pick the positive one? if x2=16⟹x=√16 or x=−√16 for respectively the positive and negative solution. This implies that the square root function has a single answer and we must negate its answer to obtain the second solution.

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)

## Why can a square root be positive or negative?

We denote the positive root (which we often call the square root) by √a. The negative solution of x2=a is −√a (we know that if x satisfies x2=a, then (−x)2=x2=a, therefore, because √a is a solution, so is −√a).
