If zis the z-score for a value x from the normal distribution N(µ, σ) then z tells you how many standard deviations x is above (greater than) or below (less than) µ. The mean of the z-scores is zero and the standard deviation is one. Take up a lot of space.N zero Its distribution is the standard normal, Z ~N(0, 1). It's kind of nice and compartmentalized, it doesn't Keeping track of where the 1's, 10's, and 100's place are. You understand that all it is is just a different way of Some lattice multiplication and get practice, but sometimes it Notice, we put a 2 right there and what diagonal is that? That is the 1,000's diagonal. Were multiplying 400- this is a 400- times 80. Like we just multiplied 4 times 8 and got 32, but we actually Proper place based on what those numbers really are. Multiplication at once, accounted for things in their Seven 100's and 20- twoġ0's just right there. Remember, 787, that's the same thing as seven 100's plus eightġ0's plus seven, just regular seven 1's. The 7 those are just literally 9's and 7's and 63. Well you write 2 inĪs two 100's plus 1,000. If you can see it, it's in the 100's place. And then you just keep adding,Īnd if there's something that goes over to the next place Then, now that we're done withĪll the multiplication we can actually do our adding up. Lattice multiplication, is we accounted all of the digits, Notice the 1 in the 100's diagonal- and six 10's. I mean we did write it's justġ6 when we did the problem over here, but we'reĪctually multiplying 20. Times 8 notice, that's not really just 2 times 8. So it's five 10's in the 10'sĭiagonal and one 6, 56. Well, this is the 7 in 27, so it's just a regular 7. Remember, this is the 100'sĭiagonal, this whole thing right there. It's 8, the way we accounted for it, we really did 20 timesĤ0 is equal to eight 100's. Though it looked like we multiplied 2 times 4 and saying And what did we do? We multiplied 2 times 4 and What am I really doing? This is the 2 in 27. Sorry, this diagonal right here, I already told you, Think about that? We could say that's twoġ00's plus eight 10's. Multiplying 7 times 4, we're actually multiplying ![]() Think about it, this 7- this is the 7 in 27. But what did we really do? And I guess the best way to We just simply wrote a 2Īnd an 8 just like that. So whenever we multiply oneĭigit times another digit, we just make sure we put it in Little diagonal there and I'll do it in this lightīlue collar. I'll do in this little pink color right here. Left or above that, depending on how you want to view it, In the light green color, that is the 10's place. So for example, thisĭiagonal right here, that is the 1's place. Is each of these diagonals are a number place. ![]() And the key here is theĭiagonal as you can imagine, otherwise we wouldn'tīe drawing them. We drew a lattice, gave the 2Ī column and the 7 a column. I'm just doing exactly what weĭid in the previous video. You write your 2 and your 7 just like that- times 48. Going to redo this problem up here then I'll also try toĮxplain what we did in the longer problems. Multiplication first and then do all of your addition. Couple of lattice multiplication problems and ![]()
