Answer

$\underline{\text{negative}}$

Work Step by Step

Read and observe the following situation: $1 \lt 3$ Multiplying $-2$ to both $1$ and $3$ gives $-2$ and $-6$, respectively. Note that $-2 \gt -6$. Notice that when a negative real number is multiplied to both sides of an inequality, the inequality symbol changes to the opposite direction (or flips). Thus, the missing expression in the given statement is $\underline{\text{negative}}$.
