It is used when a square root or any root of multiple of 2 is used to find the root . It means plus minus.
but he says no...
It is correct bcoz √4=+-2 as +2×+2=4 and -2×-2=4 so it's correct
yeah
but when firefury said that it should be side ways he said no.. that is why i did not answer

Hai friend ,
It is "plus or minus" sign
It is used in maths,where the situation has many probable outcomes.
It is also used when finding square root
The plus-minus sign (±) is a mathematical symbol with multiple meanings. In mathematics, it generally indicates a choice of exactly two possible values, one of which is the negation of the other.
Eg:-
3±2=3+2=5 or 3-2=1
√4=±2=+2=-2
