PLEASE REFER TO OUR PROOF : WATCH HERE!

When faced with math problems like these, most of us immediately reach for a calculator or pen. Imagine if you could do these and other seemingly difficult things. You have calculations in your head. It seems like an impossibility. It is not.

Mental math calculations are one of the keys to improving and expanding your math potential. A gateway to success in understanding and mastering higher mathematical fields is to solve basic math problems in your head. It is a skill that offers lifelong benefits.

• giving you a competitive edge in school or at work;
• keeping your mind active and sharp at any age;
• improving your performance on standardized tests; and
• learning to solve problems by using a variety of methods.

Mental mathematics can be useful when shopping for groceries or figuring out how much to tip. And perhaps the best part? One of the most engaging and entertaining members of The Great Courses faculty is Professor Arthur T. Benjamin of Harvey Mudd College. Mental math has secrets. The new 12-lecture course is designed to help you improve and enhance your ability to solve a range of mathematical problems.

Mental math is simple.

Professor Benjamin shows that mental math is not difficult. You may not know it, but it is an ability you already have. It is a process of breaking down a large problem into simpler and simpler problems until it is finally reduced to a single answer.

Professor Benjamin assumed no detailed knowledge of mathematics other than what you learned in elementary school. Mental math has secrets. To be accessible to anyone who wants to strengthen his or her mental calculating skills.

The basic nuts-and-bolts operations of mental mathematics are the focus of the first part of the course.

• Adding any two numbers up to three digits
• Subtracting any two numbers up to three digits
• Multiplying any two numbers up to two digits
• Dividing any number by a number up to two digits

Dr. Benjamin fills each lecture with a wealth of practice problems to follow along with and get you engaged in the joys of mentally solving math problems.

• how to find approximate answers using the art of “guesstimation”;
• how to quickly find squares and square roots;
• how to improve your memory for numbers (including phone and credit card numbers) by using a simple phonetic code;
• how to approach enormous calculations with increased confidence and accuracy;
• how to mentally determine the day of the week of any date in history; and
• how to do rapid pencil-and-paper mathematics in ways seldom taught in school.

You can use the additional problems in the course guidebook to practice your newfound skills.

There are valuable mathematical tips and techniques.

Throughout. Mental math has secrets. Professor Benjamin shows you how to tackle specific mathematical calculations. For determining the divisibility of any odd number that doesn’t end in 5, he calls it create a zero, kill the zero.

Is it a multiple of 7?

• Start by adding or subtracting a multiple of 7 to create a 0 at the end (1232 28 = 1260).
• Kill the 0 from the new number (1260 becomes 126).
• Add or subtract a multiple of 7 to create another zero at the end (126 14 = 140), then kill the 0 at the end.
• Determine whether the new number is a multiple of the original divisor (yes, it’s 14).
• Thus, 1232 is a multiple of 7.

There is an encouraging and rewarding look at numbers.

You will get more than just fun strategies to help with mental math. Learning with Professor Benjamin is like having a coach by your side who will encourage you, challenge you, and instill mathematical confidence in you. He has won a number of prestigious awards from the Mathematical Association of America, including the Deborah and Franklin Tepper Haimo Award for distinguished college or University teaching of mathematics.

Prepare yourself for an adventure in mental mathematics. It is enjoyable, eye-opening, and rewarding. Mental math has secrets. Basic math is easier than ever before. It is a great way to take your first steps into the world of numbers.
