Intermediate Multiplication

Lecture no. 7 from the course: The Secrets of Mental Math

Intermediate Multiplication

Taught by Professor Arthur T. Benjamin | 33 min | Categories: The Great Courses Plus Online Mathematics Courses

Take mental multiplication to an even higher level. Professor Benjamin shows you five methods for accurately multiplying any two-digit numbers. Among these: the squaring method (when both numbers are equal), the "close together" method (when both numbers are near each other), and the subtraction method (when one number ends in 6, 7, 8, or 9).
