$\color{#FF6800}{ - } \color{#FF6800}{ 15 } + 10 + 4 \color{#FF6800}{ - } \color{#FF6800}{ 1 }$
$ $ Find the sum of the negative numbers $ $
$\color{#FF6800}{ - } \color{#FF6800}{ 16 } + 10 + 4$
$- 16 + \color{#FF6800}{ 10 } \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
$ $ Add $ 10 $ and $ 4$
$- 16 + \color{#FF6800}{ 14 }$
$\color{#FF6800}{ - } \color{#FF6800}{ 16 } \color{#FF6800}{ + } \color{#FF6800}{ 14 }$
$ $ Add $ - 16 $ and $ 14$
$\color{#FF6800}{ - } \color{#FF6800}{ 2 }$
