  • Evaluate the expression: -15-|15-|-15||


\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}


\sf \: -15- \left| 15- \right| -15 \left| \right|

The absolute value of a real number 'a' is 'a' when
\sf\:a\geq 0, or '-a' when a < 0. The absolute value of -15 is 15.


\sf \: -15-|15-15|

Subtract 15 from 15 to get 0.


\sf \: -15-|0|

The absolute value of a real number 'a' is 'a' when
\sf\:a\geq 0, or '-a' when a < 0. The absolute value of 0 is 0.


\sf \: -15-0

Subtract 0 from -15 to get -15.


\boxed{ \boxed{ \bf \: -15 }}
