Answer 2

$\large \fbox{ \red{❃}{Required \: Solution:}}$

${1) \: 35 - (20)}$

$\blue{= 35 - 20}$

$\blue{ = 15}$

$2) \: ( - 15) - ( - 18)$

$\blue{ = (- 15) + 18}$

$\blue{ = 3}$

$3) \: 23 - ( - 12)$

$\blue{ = 23 + 12}$

$\blue{ = 35}$

$4) \: 72 - (90)$

$\blue{ = 72 - 90}$

$\blue{ = 18}$

$5) \: ( - 20) - (13)$

$\blue{ = ( - 20) - 13}$

$\blue{= 33}$
