Every positive number has two square roots . . . the same number with both signs.It's possible that you may not need both of them. In a Physics problem, for example,or in a motion problem (When do two trains meet ? etc.), or a math word problem,the negative one often makes no sense and you just ignore it. But as far as the mathalone is concerned, both of them are always there.
It makes the number smaller. For Example: 20 x .5 = 10
Not necessarily. For example, if you multiply one million by 0.001 (which is a positive number), you get a thousand, which is less than a million.
