Everyone knows that whenever we square a negative number it becomes positive but everyone just accepts this as a universal truth. I want to know why this happens? I also want to know as to why do two negatives make a positive? And moreover is (-2)^2=4=(2)^2 then how will be justify that this does not make -2=2 ?
