Hi, Andy Blackett here, I've taken a break from making Mobius Strips and Klein Bottles hewn from solid gold and am spending my evening watching your Decision Maths videos. One of my students mentioned that you had produced these, great to see them being enjoyed although i'm not sure you give enough attention to the rules of flower arranging at 23:22! Glad you have enjoyed using the powerpoints. Andy

In 2 weeks time I have my AS exams for D1, CP1 and FM1. Thank you for making these videos they've been helpful at times when my textbook and teacher couldnt help me 👍

Hi, Miss. I have my D1 exam today. All of your videos were really helpful for revision. I love all of them. You have made everything so clear and easy to understand. This playlist definitely deserves more recognition. I hope you have a wonderful day, thank you for great lessons😊💖

There's a mistake at 1:24:23. The vertices of the box on the graph are (14, 16), (16, 16), (14, 18) and (16, 18). Each box is 2 units in x and y, not 1. The y-coordinate of the intersection is 17.14, so there is no way that would be in the middle of 17 and 18. Not that big of a deal though, which is probably why you didn't notice :).

for 59:41 can you please explain how you got p=36 and how you got the x and y coordinates

Hello, why do we have to add the constraints 0≤x, 0≤y when we already have them in constraints? e.g. 10≤x≤80, 5 ≤y ≤ 40 [22:16]

Your videos certainly help clear up my misconceptions. I do have one question tho - must an objective line always have a negative slope? i.e. never in the form of A = -3x + y?

01:24:34 no its actually (14, 16) look at the y axis its in a scale of 2 up each box. It doesn't matter in the long run. But its theses kinda silly mistakes that I lose most of my marks in exams.

Sorry, how different is edexcel ial to edexcel normal a level?

[mrfreerunners]

is this a whole lesson on a whole chapter ?
