Formula
Calculate the value
$- \dfrac{ 1 }{ 18 } - \left( - \dfrac{ 3 }{ 8 } \right) \div \left( - \dfrac{ 3 }{ 10 } \right) \times 1 \dfrac{ 1 }{ 3 }$
$- \dfrac { 31 } { 18 }$
Calculate the value
$- \dfrac { 1 } { 18 } - \left ( - \dfrac { 3 } { 8 } \right ) \div \left ( - \dfrac { 3 } { 10 } \right ) \times \color{#FF6800}{ 1 \dfrac { 1 } { 3 } }$
 Convert mixed number into improper fraction 
$- \dfrac { 1 } { 18 } - \left ( - \dfrac { 3 } { 8 } \right ) \div \left ( - \dfrac { 3 } { 10 } \right ) \times \color{#FF6800}{ \dfrac { 4 } { 3 } }$
$- \dfrac { 1 } { 18 } \color{#FF6800}{ - } \left ( - \dfrac { 3 } { 8 } \right ) \div \left ( \color{#FF6800}{ - } \dfrac { 3 } { 10 } \right ) \times \dfrac { 4 } { 3 }$
 Since negative numbers are multiplied by an even number, remove the (-) sign 
$- \dfrac { 1 } { 18 } - \dfrac { 3 } { 8 } \div \dfrac { 3 } { 10 } \times \dfrac { 4 } { 3 }$
