Question 1179469: Two matrices can be multiplied only if their sizes are compatible. Suppose that U is an m × n matrix, and the V is a p × q matrix. In order for the matrix product UV to make sense, what must be true about the dimensions of these matrices?

n=p

Basic matrix rules.

The number of entries in each row of U (i.e., the number of columns in U), which is n, must be the same as the number of entries in each column of V (i.e., the number of rows in V), which is p.
