Sobre este producto
- Learn how to perform mental calculations in just a few seconds! In this book, you will learn techniques that will help you perform addition, subtraction and multiplication and calculate squares, cubes and square roots. You will also learn how to calculate all the decimal digits of all the divisions with divisors up to 50 or even higher. This book is in sharp contrast to the prevailing trend nowadays, as the vast majority of people prefer to use a calculator or a mobile phone for any calculation, even the simplest ones. However, performing mental calculations has several advantages. The most obvious one is the advantage of exercising your brain. In addition, the fast execution of mental calculations is especially useful during exams in school or in university, where students usually face time pressure. Apart from being time-consuming, it can also be disruptive to frequently interrupt the process of solving a problem in mathematics or physics to use a calculator or perform calculations on paper. Those who perform mental calculations may also receive some unexpected gifts in their life. Some companies test their candidates on their ability to perform fast calculations. Moreover, those who execute fast calculations are more likely to get hired in the first place, but also more likely to be effective contributors later, create positive impressions, and earn the respect of their supervisors/colleagues or professors/fellow students if in an academic environment. Examples of calculations you will be able to perform after reading this book: 85 2 = 7225 145 2 = 21025 28 3 = 21952 89∙68 = 6052 11∙7624 = 83864 5 / 7 = 0.142857 12 / 19 = 0.6315789… 1 / 1024 = 0.009765625 √2409 ≈ 49.08 As soon as you become adept at performing mental calculations, you will greatly accelerate the solving process of daily problems that show up at work and in life and you will become more confident in solving any problem. Get ready to become a mental math genius!
