Anyone know how to minimize the following functions using the K-map ?

f(A,B,C,D) =  m(0,1,2,8,9,10,11,12,13,14,15)

I dont really understand the function and what is the "m" stand for ?

Re: K-map

I think the little m stands for sum of products. Its usually written as $$\sum$$ m (number, number, number)

Product of sums would be written with a capital M.

Do you know how to solve K maps like that?

Its basically saying put a 1 in the squares that coorespond to the binary numbers 0,1,2,8,9, etc. You can also tell that its 4 variable K map.
