Now over here we've been given two matrices.
00:03
The matrix a is given to us as the elements.
00:07
I'm just noting down the entries.
00:09
Minus 1, minus 4, 0, then come 6, 5 and 3.
00:17
Okay? this is one matrix.
00:19
The other matrix that is noted by b is 203 and 9.
00:26
Okay? we've been asked to find out the product matrix that is, now the question arises how do we find out the product matrix? so for that my dear friends it's really very simple what you're supposed to do over here is you just have to find the entries of the product for that just multiply each row of matrix a by each column of matrix b.
00:52
I'm going to explain how we are going to do this okay so let's come back over here now now as i say we are going to multiply each row of the first matrix by each entry of the column of the second matrix.
01:08
So see, i'm making an arrows for your convenience.
01:11
Okay.
01:12
So that gives you minus 1 times 2 plus 6 times 0, right? similarly, if we talk about the second entry, that means minus 1 times 3...
