Answer 2

Answer:

$\left(3+13\right)\left(3-73\right)=-1120$

Step-by-step explanation:

$\left(3+13\right)\left(3-73\right)$

$\gray{\mathrm{Follow\:the\:PEMDAS\:order\:of\:operations}}$

$\black{\mathrm{Calculate\:within\:parentheses}\:\left(3+13\right)}$

$3+13$

$\gray{3+13=16}$

$=16$

$=16\left(3-73\right)$

$\black{\mathrm{Calculate\:within\:parentheses}\:\left(3-73\right)}$

$3-73$

$\gray{3-73=-70}$

$=16\left(-70\right)$

$\black{\mathrm{Multiply\:and\:divide\:\left(left\:to\:right\right)}\:16\left(-70\right)}$

$16\left(-70\right)$

$\gray{\mathrm{Apply\:rule\:}a\cdot \left(-b\right)\:=\:-a\cdot \:b}$

$\gray{16\left(-70\right)=-16\cdot \:70=-1120}$

$=-1120$
