Okay. Looking good needs to make. Cease on. We want to find 83 months to a B s. So first off we'll do a B. So it would be too much matrix because we're multiplying to two by two major seats on you have to take for each corresponding out, Theo Corresponding road from the first matrix on column from the 2nd 1 So, for example, first breakfast column would be fast rope against the color. Nine times four is 36 minus four times minus seven is gonna be positive. 28 on their 28 to 36. Well, that's going to be equal to 64. Okay, 60 fours, in your estimation, on its 1st 2nd column, Zeros that nine minus four lots that fires minus 20. Newmont are second road out seven lots of about four. And there might be three blocks that my seven Serie we're gonna have total off. Seven. Lots of seven, which I hate on. Then finally, second road second columns were lots that seven minus three locks that five minus 15 on. This is our a big okay now on. Except you need to you three B minus two and so under constant threat of our matrix, you just time to every single one of the elements by our constant cross. Refer to this as a scaler, say three times that force 12 times anything is zero minus seven times three minus 21 on the 53 50. Equally for are a matrix We've got to us off 9 18 Do not scoff. 4827 is 42 lattes minor, straight past minus six on. But we're doing a possible minus matrix operation. You just do each element the operation with corresponding element in your nature. So, for example, the first row first column just 12 minus 18 which give you my six next up because you're a minus, minus eight second Rhodes College 1st 2nd rate. My 21 minus 17 months. 21 of my 70. You should end up months 38 on. And finally, we've got our 2nd 2nd row, second collar. You've got 21 lots of eggs. You've got months. An A minus on. Then you're gonna minus six lots off. 15 from that. And that should just come out back to 78. Okay, not only we've got our be a three. So this time be says, we're taking the roads big and in the column today. So first row, first column, bathroom big. It's best card. Just got full. What's that? Nice to be fair to six. Uh, next for, uh, get your first round of second column. Zeros that honest? Uh, sir. First, right against second color You've got arthritis from. I'm sorry. You've got because here you've got first broke it, then you've got birthrate. Get set color for lots of likes for my 16th. Sorry. Got a bit of confusion there. Uh, Okay, now, So even onto the second road for big second with minus 75 against 97 minus seven lots off nine. And then you're gonna have seven lakhs. If I'd say you've got minus nine lots is seven years, we can say five or six minutes, minus four lots of seven, which ah, Hignett is equal to minus 28. So get, uh here. We had my 75 against 97 So you end up with a net off minus 47 Okay. And and so we've got the second row second column minus seven lots off minus four, which is 28 on. We've got five of my three minus 15. Which shift? Leave us at 13. So our final trip stay six months. 16 might create 13 on These are our three result in major cities.
