Why is it impossible to get a negative answer when you square any number?

V kno that- x- is +. Now when u sqare a negative no it means occouring 2 times and cancel out each other.

For example-

-2 x -2=4

============================ (a second answer.)

Every real number is either negative, positive or zero.

When you square a number, you multiply it by itself, so if

you square a negative number, you are multiplying a negative by a negative which gives a positive. If you square a positive, you multiply a positive by a positive and get a positive. If you square 0 , get 0. Therefore, in no case is the answer negative.

( It is harder to explain why a negative times a negative is positive.)
