For each multiplication, count the number of columns for the first table and the number of rows for the second table. If they are equal, the multiplication is valid. Otherwise the product it is undefined.

CD = 3,1 1,2 is valid DB = 1,2 2,2 is valid AB = 3,2 2,2 is valid BB = 2,2 2,2 is valid i think thats all the valid ones

For the AB multiplication. A has 2 columns, B has 2 rows, so the multiplication is valid. You do the same thing for the rest.
