Variety of size, colour and quality same with our life "colourful"

Then I Understand..............................................


I have 1 big problem = P(1)


then came another 1 small problem = P(2)


then came another 1 bigger problem = P(3)


then came another 1 biggest problem = P(4)


Current total of my problem = P(1) + P(2) + P(3) + P(4) = "I got 4 problem with variable range"


Then i understand if i keep counting on how much problem that i have, its mean i keep (+) my problem all the time.... without any intention to (-) it...... so now I should have calculator in my room because i gonna use "-" , "/" in my life....
