Answer 1

Answer:

$345$

Step-by-step explanation:

$7-\left(-19\right)-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$7+19-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$26-18+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$8+\left(-19\right)+187-\left(-19\right)-18+\left(-19\right)+187$

$8-19+187-\left(-19\right)-18+\left(-19\right)+187$

$-11+187-\left(-19\right)-18+\left(-19\right)+187$

$176-\left(-19\right)-18+\left(-19\right)+187$

$195-18+\left(-19\right)+187$

$177+\left(-19\right)+187$

$177-19+187$

$158+187$

$=345$
