if(isnumber) con múltiples celdas

I am using the following logic function =IF(ISNUMBER(B5),B5*B2,"") which works great but what I need is if B5 is blank the formula must go on and check C5 for a number to be multiplied similarly. I realise the following formula has too many arguments but hopefully someone out there can steer me in the correct direction.

=IF(ISNUMBER(B5),B5*B2,(ISNUMBER(C5,C5*B2,""))

Try this, it's an embedded if function

=IF(ISNUMBER(B5),B5*B2,IF(ISNUMBER(C5),C5*B2,IF(ISNUMBER(D5),D5*B2,"")))
