Please, who knows what's the difference between the product of q and |q| and q square? Why does it need |q|???? And I can't write down q square?? How come?
Please someone tells me!!

the "sticks" around the q mean absolute value (how far away the number is from zero), so whatevers inside them is positive. if q is for example -2, than IqI equals 2. And q X IqI= -4. q squared would be 4.

If q is a negative number, q squared would be positive, but the product of q and |q| would be negative.

according to definition 1q1=q if q>0 and it is equal to -q if q <0 then qx1q1 =q square if q>0 and it is equal to qx(-q) if q<0

q times |q| = +/- q^2
it can be positive or negative.
q squared is always positive.
