Find the sum of the negative numbers
$\color{#FF6800}{ - } 3 \color{#FF6800}{ - } 4$
$ $ Put negative numbers in parentheses $ $
$\color{#FF6800}{ - } \left ( 3 + 4 \right )$
$- \left ( \color{#FF6800}{ 3 } \color{#FF6800}{ + } \color{#FF6800}{ 4 } \right )$
$ $ Add $ 3 $ and $ 4$
$- \color{#FF6800}{ 7 }$
