At an interview, a famous soccer star was reported to have said, "if I am not playing soccer, I am watching soccer. If I am not watching soccer, I am reading about soccer." Assuming that the statements are all true and that only one activity can be engaged at any one time, what was the famous soccer star doing at the interview?

Any help is appreciated. Thank you.

I was working in class today, and as I am not a maths teacher, I pondered on the different letters that were being used from the Greek alphabet, and I thought about algebra when we use symbols to represent something. I wondered what symbols the Greeks use.

1/3(x-2)=2/3x - 13/3

6/3x - 6/6= 2(6)/3x - 13(6)

2x - 1 = 4x - 26

2x - 4x = 1-26

-2x = -25

x = -25/-2

If 20 souvenirs are to be divided among 4 candidates with each getting at least three, I think the answer is the coeff. of x^20 in the expansion of (x^3+x^4+......+x^20)^4. What will be the answer if the constraint of minimum souvenirs is removed? Please explain how this bracket is arrived? Please also give some more such examples. I think one of these is: in how many ways one can get m marks in aggregate if there are x papers of n marks each.
