Question

Give the sum of (-8)×(-2)×3×(-5)

Answer 1

Answer:

$\left(-8\right)\times \left(-2\right)\times \:3\times \left(-5\right)=-240$

Step-by-step explanation:

$\left(-8\right)\times \left(-2\right)\times \:3\times \left(-5\right)$

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

$\gray{\mathrm{Multiply\:and\:divide\:\left(left\:to\:right\right)}\:\:}$

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

$\gray{\left(-8\right)\times \left(-2\right)=8\times \:2=16}$

$=16\times \:3\times \left(-5\right)$

$\gray{16\times \:3=48}$

$=48\times \left(-5\right)$

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

$\gray{48\times \left(-5\right)=-48\times \:5=-240}$

$=-240$
