Calculate the value
$6 \color{#FF6800}{ - } \color{#FF6800}{ 4 } \color{#FF6800}{ \times } \left ( \color{#FF6800}{ - } \color{#FF6800}{ 1 } ^ { \color{#FF6800}{ 2 } } \right )$
$ $ Simplify the expression $ $
$6 + \color{#FF6800}{ 4 } \color{#FF6800}{ \times } \color{#FF6800}{ 1 }$
$6 + 4 \color{#FF6800}{ \times } \color{#FF6800}{ 1 }$
$ $ Multiplying any number by 1 does not change the value $ $
$6 + \color{#FF6800}{ 4 }$
$\color{#FF6800}{ 6 } \color{#FF6800}{ + } \color{#FF6800}{ 4 }$
$ $ Add $ 6 $ and $ 4$
$\color{#FF6800}{ 10 }$
