Question

IS THIS TRUE OR FALSE!

Matrix A has dimensions 2 x 3. Matrix B has dimensions 3 x 6. These two matrices can be multiplied to find the product AB.

Answer 1

It's true. Just know that when multiplying matrices the last dimension of the first matrix and the first dimension of the second matrix have to be the same. For example, you can multiply a 1 x 12 matrix and a 12 x 3 matrix, because 12 and 12 equal.

Answer 2

thanks :) i really don't understand matrix any more than basic adding and subtracting them.

Answer 3

But they have to be in that order. For your question if it were asking if you could find the product of BA, you can't. Notice that Matrix B and A line up like this when multiplying BA,
3 x 6 multiplied by 2 x 3, there the 2 and 6 are not equal so they can't be multiplied in that order.
