Why does negative 2 squared equal negative 4?
Because negating a positive number gives a negative number, and squaring any number is always positive. 22 = 4 → -(22) = -(4) = -4. But note: (-2)2 = 4 ≠ -4. It is very important that when giving your question you are clear to where the negative is attached.
Will positive numbers always have a higher absolute value than the negative numbers and WHY?

Is the absolute value of any non zero number is always positive?
yes
Is the reciprocal of any positive or negative integer always a rational number?
Yes, it is.
In any distribution is the sum of the squared deviations from the mean always equal to zero?
