In a school, there are "m x n" students. On October 2, 2014, all the students of the school were asked to assemble at the school ground. The students stood in 'm' rows, with 'n' students in each row. Each student was allotted a position number denoted by P(a, b), where 'a' and 'b' represent the row number and the column number in which the student was standing. Each student gave 'a' toffees to every other student if 'a' was not more than 'b', and he/she gave 'b' toffees to every other student otherwise. If m = 3 and n = 5, find the total number of toffees that exchanged hands.
