 We have defined a KxMxN MAC unit as a device which takes K signed M-bit numbers ($a_0, a_1, ..., a_{K-1}$) and K signed N-bit numbers ($b_0, b_1, ..., b_{K-1}$), and computes 
-$$ a_0*b_0 + a_1*b_1 + ... + a_{K-1}*b_{K-1} $$
+$$a_0*b_0 + a_1*b_1 + ... + a_{K-1}*b_{K-1}$$
 
 For making an KxMxN MAC unit, the number of output bits will be
 $$\lceil\log_2(K * 2^M * 2^N)\rceil = \lceil\log_2 K\rceil + M + N$$
