Consulting Mental Math Practice: Simplifying Complex Calculations

When it comes to case interviews, being able to perform complex calculations mentally can be a major advantage. However, many people find themselves intimidated by the thought of doing large-scale math without a calculator. But with some practice and knowledge of shortcuts, you can easily simplify these calculations and impress your interviewer with your outstanding mental math skills.

One common technique for simplifying calculations is to not write out every zero when dealing with large numbers. For example, let's say you're asked to calculate the revenue of a company that sells 25,000 units per year at $32 per unit. Instead of writing out '25,000' and then adding it to the result of (32 × 25), you can simply write down the calculation as ($32 × 25). This may seem like a small difference, but it can make a big impact when dealing with larger numbers.

Another key aspect of case interviews is being aware of the properties of Case Numbers. These numbers usually have certain characteristics that can make calculations easier if you know how to take advantage of them. For example, many Case Numbers are round numbers with only a few significant digits. This means that you can use these numbers to your advantage when performing calculations.

In addition to simplifying calculations, practicing mental math is also an important part of preparing for case interviews. The best way to do this is to practice solving problems with numbers representative of actual Case Numbers and to be familiar with the types of problems you're most likely to encounter. By doing so, you'll become more comfortable with performing complex calculations mentally and will be able to impress your interviewer with your outstanding mental math skills.

By using shortcuts like not writing out every zero and being aware of the properties of Case Numbers, you can easily perform large-scale math without a calculator. With practice and knowledge of these shortcuts, you'll be well on your way to impressing your interviewer with outstanding mental math skills.
