Subject: adding, multiplying array

Hi.

I want to multply all elements of two arrays and add that to all elements of 
the third array like this:

c+=a*b

c=[1,1,1]
a=[2,2,2]
b=[3,3,3]

c=[7,7,7]  # (1+2*3)=7

I tried (found on google):

a.zip(b).map {|i,j| i*j} (don't really know how that works)

and how to add that to c array ?

Thanks
