Question

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

Answer 1

$\\ \sf\longmapsto -15-|15-|-15||$

$\\ \sf\longmapsto -15-|15-15|$

$\\ \sf\longmapsto -15-|0|$

$\\ \sf\longmapsto -15-0$

$\\ \sf\longmapsto -15$

Answer 2

$\huge \boxed{\mathfrak{Question} \downarrow}$

• 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.

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