5. Kanga wants to multiply three different numbers from the following list: $-5,-3,-1,2$, 4,6 . What is the smallest result she could obtain?
A -200
B -120
C -90
D -48
$\mathrm{E}-15$
SOLUTION
B

The result furthest from zero is obtained by multiplying the three numbers furthest from zero, namely $-5,4$ and 6 . This gives -120 , which is negative and hence is the smallest possible result.
