Answer:
=SUM(C2:C4, C7)
Step-by-step explanation:
In excel 'C' represent the cell ( intersection of row and column ),
Also, '=sum( )' represents the function of addition in the excel,
Also, when we operate all consecutive cells from [tex]Cn[/tex] to [tex]Cm[/tex]
Then under the function formula we write [tex]Cn:Cm[/tex]
And, when we operate a cell [tex]Cn[/tex] with non consecutive cell [tex]Cl[/tex]
Then under the function formula we write [tex]Cn, Cl[/tex]
Hence, C2+C3+C4+C7 can be written as,
=SUM(C2:C4, C7)
