It is now common to define 3×4 to mean 3+3+3+3,
i.e.; to add the number three together four times. When multiplication is defined this way, the number on the right
(4) is called the multiplier meaning the number of times the number 3 is added together. By the commutative property of addition,
3x4 is equal to 4x3. In our video #3, Herb writes the problem 3+3+3+3 as 4x3 in order to illustrate the algorithm for
multiplication in a more natural way. Notice that 4 (the multiplier) is in the first position. Do not let this confuse
you - they are equivalent definitions.
