Answer 1

Step-by-step explanation:

[-63-(-33)] + [-9-(-46)]

= (-63+33) + (-9+46)

= (-30) + (37)

= 7

Answer 2

Answer:

$\left[-63-\left(-33\right)\right]+\left[-9-\left(-46\right)\right]=7$

Step-by-step explanation:

$\left[-63-\left(-33\right)\right]+\left[-9-\left(-46\right)\right]$

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

$\mathrm{Calculate\:within\:parentheses}\:\left[-63-\left(-33\right)\right]$

$-63-\left(-33\right)$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:\:$

$\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a$

$-\left(-33\right)=+33$

$=-63+33$

$-63+33=-30$

$=-30$

$=-30+\left[-9-\left(-46\right)\right]$

$\mathrm{Calculate\:within\:parentheses}\:\left[-9-\left(-46\right)\right]$

$-9-\left(-46\right)$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}$

$\mathrm{Apply\:rule\:}-\left(-a\right)\:=\:+a$

$-\left(-46\right)=+46$

$=-9+46$

$-9+46=37$

$=37$

$=-30+37$

$\mathrm{Add\:and\:subtract\:\left(left\:to\:right\right)}\:-30+37$

$-30+37$

$-30+37=7$

$=7$
