I was going to solve a basic math question in a textbook.
The Suzuki family has 5 members (parents and three children.) One day they were going to take a family snapshot. How many patterns are there for them to stand side by side?
(Recently I try to draw pictures by mouse)
The answer was:
5 x 4 x 3 x 2 x 1 = 120
There are as many as 120 patterns for a 5-member family, even if they are going just to stand side by side!
There would be indeed so many dramas in a family every single day.
