Formula
Calculate the value
Answer
$\left( 2+ \sqrt{ 2 } \right) + \left( 2- \sqrt{ 2 } \right)$
$4$
Calculate the value
$\left ( \color{#FF6800}{ 2 } \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 2 } } \right ) \color{#FF6800}{ + } \left ( \color{#FF6800}{ 2 } \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 2 } } \right )$
 Get rid of unnecessary parentheses 
$\color{#FF6800}{ 2 } \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 2 } } \color{#FF6800}{ + } \color{#FF6800}{ 2 } \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 2 } }$
$2 \color{#FF6800}{ + } \sqrt{ \color{#FF6800}{ 2 } } + 2 \color{#FF6800}{ - } \sqrt{ \color{#FF6800}{ 2 } }$
 Remove the two numbers if the values are the same and the signs are different 
$2 + 2$
$\color{#FF6800}{ 2 } \color{#FF6800}{ + } \color{#FF6800}{ 2 }$
 Add $2$ and $2$
$\color{#FF6800}{ 4 }$
