− ( − 45 ) + − ( − ( + ( − ∣ − 5 ∣ ) ) ) = 45 + − ( − ( + ( − 5 ) ) ) = 45 + − ( − ( − 5 ) ) = 45 + − ( 5 ) = 45 − 5 = 40 \begin{aligned} -(-45)+-(-(+(-|-5|)))&=45+-(-(+(-5))) \\ &= 45+-(-(-5))\\ &= 45+-(5)\\ &= 45-5\\ &= 40\\ \end{aligned}

− ( − 45 ) + − ( − ( + ( − ∣ − 5 ∣ ) ) ) = 45 − ∣ − 5 ∣ = 45 − 5 = 40 □ \begin{aligned} -(-45)+-(-(+(-\mid -5 \mid))) &= 45- \mid -5 \mid \\&= 45 - 5 \\&= 40 \space \square \end{aligned}
