If both numbers have the same sign (positive|positive or negative|negative) then the result will be a positive number, otherwise we will get a negative answer:

\n

a)   $(\\var{a3}) \\div (\\var{a2})=\\var{a1}$

\n

b)   $(\\var{b1}) \\times (\\var{b2})=\\var{b3}$

\n

c)   $(\\var{b1}) \\times (\\var{c2})=\\var{c3}$

\n

d)   $(\\var{d1}) \\div (\\var{d2})=\\var{d3}$

\n

e)   $(\\var{e3}) \\div (\\var{e2})=\\var{e1}$

\n

f)   $\\var{f1} \\div (-2)=\\var{f3}$

\n

g)   There are an odd number of negatives, so:   $(\\var{g1}) \\times (\\var{g2}) \\times (\\var{g3})=\\var{g4}$
