133. dumbest math tactic

today i recall the dumbest math tactics i ever used to use.

1. the number of numbers from 0000 to 9999.
i remember the exam paper in primary school ask this kind of questions, and im so dumb i can't do it. then i devise the funniest way in my life. i use 4d to remember. 4d as in the gambling one. i remember it has 10000 numbers because in 4d has numbers from 0000 to 9999, and in chinese it is called 万字票. from the first word, it already tells you that there are 10000 numbers from 0000 to 9999. thats the lamest thing ive ever devised to help me remember.

2. special angles for trigonometry.
thanks to harily chua for teaching me this, or i will never go and memorise the special angles.


i also remember those times when i fell ill, mostly dominated by allergies and rashes. i got used to it that i only used calamine lotion instead of visiting doctors to waste my money.
the minority times i got ill was accompanied by 2 times nose bleed, 2 times vomit, 4 headaches, a few fevers, and countless flus.
happy allergy cao.
