Multiply two numbers
$\color{#FF6800}{ - } 3 \times \left ( \color{#FF6800}{ - } 3 \right )$
$ $ Since negative numbers are multiplied by an even number, remove the (-) sign $ $
$3 \times 3$
$\color{#FF6800}{ 3 } \color{#FF6800}{ \times } \color{#FF6800}{ 3 }$
$ $ Multiply $ 3 $ and $ 3$
$\color{#FF6800}{ 9 }$
$9$
