Many people do have rather poor mental math skills. In the world of smartphones and computers, why should we bother calculating numbers without aid? To succeed in a management consulting interview, however, you have to know mental math. And you need to be very good at it. During case interviews the interviewer will often test your [url=http://www.rtnagel.com/louboutin.php]louboutin pas cher[/url] quantitative skills by asking questions that require some sort of calculations (e.g. during a market sizing exercise).
Practice in mental math is necessary regardless if you are applying to a small consulting boutique firm, or a top tier firm as McKinsey, Bain, BCG or Booz. By doing a few minutes of practice every day, you can turn your mental math problems into a strength. Rad our tips below.
What should you prepare? The sort of math questions you might encounter are often quite simple. The main problem is that most candidates have not used their mental math skills since [url=http://www.gotprintsigns.com/abercrombiepascher/‎]abercrombie pas cher[/url] high school due to spreadsheets and calculators. Sometimes a candidate is allowed to do the [url=http://www.ktbruce.co.uk/barbourjackets.php]barbour jackets[/url] calculation on paper - especially if the complexity is high. You will use math skills as part of the case interview process. Say that you are answering a pricing case study. You might get a question to calculate the bottom line impact of a new price. This is a calculation that management consulting recruiters expect you to be able to solve. You need to know some quick rules for addition, subtraction, multiplication and division.
Addition
Many people will think it should be the easiest above of all calculations. But what if an interviewer asks you what 1891+1640 is, can you blurt out your [url=http://www.ktbruce.co.uk/mulberrysale.php]mulberry sale[/url] answer within 3 seconds? Well, this should not be [url=http://www.ktbruce.co.uk/barbourjackets.php]barbour.co.uk[/url] as hard as it looks if you know how to break it down and calculate them separately. Let's break this down: 1891 needs 1200 to become 3091, so 1891+1200=3091, then you just need to plus another 440 (1200+440=1640) to get the final answer, 3091+440=3531. This process [url=http://www.jeremyparendt.com/Hollister-b5.php]hollister france[/url] may seem long, but think about doing this [url=http://www.thehygienerevolution.com/hollister.php]hollister[/url] out loud. As you know that the result will be 3XXX, you can firstly say 3XXX out loud. While you say it, you can finish off the rest of calculation.
Subtraction
Generally, the basic idea is the same with addition. Let's try one, what is 6734-89? You could break it down like: 6734-100=6634, 6634+11=6645. Maybe you have realized what we are doing now - we are simplifying the calculation. But there are still so many ways to break one number down. The basic principles are: it's always easy to do with hundreds and people are more familiar with addition rather than subtraction.
Multiply
When it comes to multiply, many people will just surrender. It only takes a bit more time to master than addition and subtraction. Still, the [url=http://www.par5club.com/louboutin.php]louboutin[/url] basic idea is the same. What is 49*73? Notice that when we can't find hundreds, we look for tens. Let us break it down as: 50*73=3650, 3650-73=3577. It takes more time, but still, a lot easier. When you are doing the breaking down, you will find all the calculations follow the simple rules. The only thing you need to work on is you memory. You could also use paper as your aid.
Division
Division takes mental math to another level. The key of doing division is to find the common factor quickly. For example, what is 35/210? If you practice a lot, you will find the common factor is 7 right away. Then you divide both 35 and 210 by the common factor. This gives a new calculation: 5/30. Now you have 5 as the common factor, and a calculation of 1/6 shouldn't be hard.
Set up a practice routine After you have reviewed [url=http://www.osterblade.com]moncler outlet[/url] the basics, you need to set up [url=http://www.tagverts.com/barbour.php]barbour online shop[/url] a practice routine so you can increase the speed of your calculations. You might have some weeks before your case study interview, so spend the time wisely. Some ideas for practicing are:
1. During grocery shopping: Add all items in your basket before you head for the checkout counter and remember to include the decimals.
2. When travelling: A natural great way to practice currency conversion.
These examples are far from exhaustive, but the main point is that you need to build your practice into your daily routine, so it feels more natural for you to work with numbers. Hope [url=http://www.thehygienerevolution.com/hollister.php]hollister france[/url] this give you some good ideas on how to practice math.
