SOLUTION
From the question, it means that
[tex]\begin{gathered} a=-6,-5,-4\text{ . . . . . .3} \\ b=-4,-3,-2\text{ .. .. . . . . .4} \end{gathered}[/tex]The least possible value of a and will be a ngative number, gotten by multiplying a negative value by a positive value. So this should be
the smallest value of a, that is the -6 multiplied by the biggest value of b = 4
[tex]-6\times4=-24[/tex]Hence the answer is -24
