Answer:
[tex] \huge{ \fbox{ \tt{12}}}[/tex]
Step-by-step explanation:
[tex] \underline{ \sf{Given}} : \sf a=6, \: b=3 \: and \: c=2[/tex]
[tex] \underline{ \sf{To \: find }} : \sf{Value \: of \: the \: given \: expression}[/tex]
[tex] \underline{ \underline{ \mathfrak{Let's \: solve}}} : [/tex]
[tex] \bigstar{ \tt{ \: c \: ( \: b \: + \: a \: ) - \: a}}[/tex]
[tex] \text{Step \: 1 \: } : [/tex] Plug the values of a , b and c
[tex] \mapsto{ \tt{ \: 2 \: ( \: 3 \: + \: 6 \: ) \: - \: 6}}[/tex]
[tex] \text{Step \: 2} : \sf{ \: Add \: the \: numbers : 6 \: and \: 3}[/tex]
[tex] \mapsto{ \sf{ \: 2 \: * \: 9 \: - \: 6 \: }}[/tex]
[tex] \text{Step \: 3 \: } : \sf{ \: Multiply \: the \: numbers : 9 \: and \: 2}[/tex]
[tex] \mapsto{ \sf{18 - 6}}[/tex]
[tex] \text{Step \: 4 \:} : \sf{Subtract \: 6 \: from \: 18}[/tex]
[tex] \mapsto{ \sf{ \: 12}}[/tex]
Note : Just follow the PEMDAS rule ( See attached picture )
Hope I helped!
