Answer 2

$\\ \\ \huge \ast\sf {\color{grey}{ \underbrace \red { \: \: \: \: \: solution : - \: \: }} }\ast$

Here three numbers are given which were 9 , 3 and 12

$\\ \large\tt \: \fbox \red s \fbox \green o \fbox \blue l \fbox {\color{lime} v} \fbox \pink i \fbox \purple n \fbox {\color{darkgreen} g} \: \: \: \: \: \: \tt \red{\boxed i }\tt \fbox \red t$

$\\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \ \large\red :\longrightarrow \: 9 + 3 = 12 \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \large: \red\longrightarrow \: \cancel{12} = \cancel{12 }\\ \\ \large\red : \longrightarrow \: 0$

$\large \green\therefore \tt\red{the \: required \: answer \: is \: 0}$
