Answer
$36.36 - 28.4237 - 9.78 + 7.7$
$= 36.36 + 7.7 - (28.4237 + 9.78)$
$\underline{\ \ _1\ _1\\\ \ 36.36\\+7.70}\\\underline{\ \ 44.06}$
$\underline{\ \ \ _1\ _1\ _1\\\ \ \ 28.4237\\+\ 9.7800}\\\underline{\ \ \ 38.2037}$
$=44.06-38.2037$
$= 5.8563$
$= 36.36 + 7.7 - (28.4237 + 9.78)$
$\underline{\ \ _1\ _1\\\ \ 36.36\\+7.70}\\\underline{\ \ 44.06}$
$\underline{\ \ \ _1\ _1\ _1\\\ \ \ 28.4237\\+\ 9.7800}\\\underline{\ \ \ 38.2037}$
