Hi there,

So i have been doing few cases with peers and it's clear that math is an issue for me. I have an applied math backgroup so i understand the concepts fairly well. I am usually also good in getting the math structure, however I have been using calculators and excel forever and I am facing the following problems :

1- struggles in presenting my calculation. I have tendency to go and try the numbers, then add other numbers, rather than lay down the whole structure before calculating (I actually have the same tendency when i am doing the structure of the case study. This manfests itself as follows: I have the intuiton that some combinatin of numbers will get me somewhere, so i do the computation then decide my next step rather than the opposite. Example : a graph shows me the monthly average skier days, then nb of skiers, then i have an info about the spending of a skier.

Instead of saying Annual revenues = (sum of the monthly averge skier days ) x nb of skiers x spending per day, I have tendany to start doing computation after computation and once i get the result of one, it gives me hints about the next computation to take. My usualy way of doing this would look like "I am gonna sum the averges of each months". Once i get the result, I will say "now i am gonna multiply it by nb of skiers so i have the nb of skiers per year" and once i get that result I will say "Now i am gonna multiplay by $150, in order to get the total revenues"

2. I am still struggling in finding a clear way to lay out my calclations on my notes. It makes it stressful for me and impossible for the interviewer to follow me. it also makes it harder sometimes to come back to a given number.

I have a good memory and rely a lot on my memory to find myself though my own mess, but it's clearly not the way to go if i want to improve

3. finally nb2 also contributes in me making some mistakes sometimes. I dont think i did one case without doing at least one mistake

4. when doing peer practice cases, i realised that i am slower than most other people.

I bought V. Cheng math courses and went thruogh the material, I am also practicing basic mental math using a app on my phone. I am also trying to re learn the multiplication tabel to get things faster. I have also bought a book called Secrets of Mental math but i havent gone through that one yet

Any tips on how to improve ?
