Answer 1

Roger F is right, so this is just another way to solve this problem: For 1AM to noon:  1    2   3  4   5   6  7  8  9  10  11  12   For 1PM to midnight I will write the hours in reverse order:                          12 11 10  9   8   7  6  5  4    3   2    1   Check out the sums:                        --------------------------------------------                          13 13 13 13 13 13 13 13 13 13 13 13 = 13*12 = 156
